31.Creating a Trade System

Trade Systems are part of Formula Builder. To access them:

Click the Support or System button.
Select Formula Builder.
Click the Trade Systems tab.

Creating a trade system involves 5 steps:

Naming the system.
Naming the long and/or short trades for the system.
Establishing entry characteristics for the long and/or short trades.
Establishing exit characteristics for the long and/or short trades.
Designating a commission amount and commissions scheme (either fixed or per contract).

The limit for total combined number of entries and exits per trade system is 140.

Note: You can have multiple entries and exits for the same trade system.

Click the New button in the Systems section of the Trade Systems tab to open the Create a New Trade System window.
Input a name and an abbreviation for the new trade system.

The abbreviation appears as the toolbar button name. Additionally, CQG uses the abbreviation name when you use one trade system as the basis for another trade system.

By default, CQG automatically uses the first seven characters of the system name as the abbreviation. However, you can change the abbreviation:

Click in the Abbrev: box.

Enter the desired abbreviation name.
Select the Toolbar button checkbox to place a button on the application-specific toolbar, allowing users to display the trade system in a chart window with one click.
Click the OK button to save the new name and abbreviation and close the Create a New Trade System window.

32.Adding a Note to the Trade System

Users can easily enter a note about a trade system or trades within the trade system.

Click either the Note button associated with the trade system name or the Note button associated with the trades for the trade system.
Enter the desired note text.

33.Naming the Trades Associated with the Trade system

The second step involved in defining a Trade system is to name the trades comprising the system.

Click the New button in the Trades for System section.
Enter a name for the new trade.
Click the OK button to record the new trade name and close the Create a New Trade window.
Select the type of trade from the dropdown list in the Use As section.

Choices include Long, Short or Off.

If Off is selected, the trade will still be part of the current trade system but will not be considered in the current evaluation.

34.Designating the Order Type

The first step in establishing the entry characteristics is designating an entry signal.

Click the Entry tab.
Select the Order Type.

35.Designating the Order Characteristics

Select one or more of the Allow multiple entries before exit (Pyramids) and/or Allow entry on exit boxes.

Selecting the Allow multiple entries before exit checkbox allows positions to accumulate without being closed until the exit signal becomes true.

Selecting the Allow entry on exit checkbox allows entries and exits to occur on the same bar. When the box is not checked the system will wait at least until the next bar before generating an exit signal.

36.Potential Timeframe Problem in Trade systems Formulas

Because some values (high, low, and close) are not known until after a market's close, you can set up a trade system that will appear to be extremely successful, but won't work in reality. The following examples illustrate what can happen:

Example #1: In this example, the system is set up to enter on today's Open (the Order Type button) whenever today's close is greater than yesterday's close. However, you won't know the value of today's close until after the close occurs, so you can't truly base entry decisions on that future event.

The graph shows the results of implementing this trade system. It reports a great profit profile. Unfortunately, it doesn't work like that in reality.

Example #2: This example illustrates a less obvious time-based mistake. Once again, the system is set to Enter on Open. This time the signal is based on an RSI.

While that might be fine, in this case, there will be a problem because the RSI is based on the closing price.

$c:\users\sophiaj\appdata\local\temp\snaghtmlb88570f4.png$

Once again, you have extremely profitable results reported in the graph below, but that's because it reflects decisions that are based on future events, as a result of the RSI having a closing price parameter, while the trade system has an Open order type.

If you see remarkably profitable results reported by your trade system, check all your values to be sure your trade system isn't acting on information you won't have in real-time.

37.Designating the Entry Signal

Click the Signal tab to define the actual entry signal.
Trade system signals are defined using the Formula Toolbox, exactly the same way Q Formulas, Conditions, User Values and Custom Studies are specified.
Click the Toolbox button.
Insert the desired elements from the Formula Toolbox.

Note: Signals yield true or false values.

38.Designating the Entry Price

Click the Price tab.
Designate the price (using the Formula Toolbox) to be used for the entry signal.

A price can only be designated when either a Stop or a Limit order has been designated as the order type, since Open and Close already refer to a specific price.

The price designation operates in conjunction with the signal designation. In other words, the price parameter tells the system where to execute the order once the designated signal becomes true.

39.Designating a Quantity

Click the Quantity tab.
Input the quantity for each trade.

40.Designating Exit Characteristics

Similar to defining the entry characteristics, you must define the exit characteristics for each trade in the system. Like the entry criteria, designating the exit criteria involves specifying an order type, designating the Signal, Price, and Quantity. However, unlike the entry characteristics, you may designate more than one exit for each trade system.

Defining a New Exit

Select an order type. Choices include: Open, Stop, Limit or Close.
Click the New button. The Create a New Exit window opens.

$c:\users\sophiaj\appdata\local\temp\snaghtmlb897808e.png$

41.Enter a name for the new exit.

42.Select the type of exit. CQG offers 6 types of exits:

Custom

Money management

Break even

Dollar risk trailing

Percent risk trailing

Profit target

Entry stop

43.Select either or both of the checkboxes. Allow entry on exit allows entries and exits to occur on the same bar. Allow more than once allows more than one exit to occur on the same bar.

44.Click OK.

To copy an exit

You can copy previously created exits and use the old exit as the basis for a new exit signal.

Select the exit to be copied.
Click the Copy button to open the Copy an Exit window.
Enter a name for the new exit.
Click OK.

The newly created exit appears at the bottom of the Exits for Trade section of the Exits tab. Modify the exit using the Formula Toolbox.

Note: You can only copy previously-created custom exits.

You can also easily delete a trade exit.

To delete an exit

Select the exit.
Click the Delete button in the Exits section for Formula Builder.

45.Types of Exit Signals

$c:\users\sophiaj\appdata\local\temp\snaghtmlb89c57e9.png$

You must define an entry and an exit for each trade in your system.

CQG offers 6 types of exit signals and allows you to define multiple exit signals for each Trade system.

To define an exit signal

Click the Exits tab.
Select an Order Type.

Choices include Open, Stop, Limit or Close.

46.Click the New button in the Exits for Trade section to open the New Exit window, which allows you to specify one of 7 types of exits.

47.Click the Copy button to use a previously defined exit signal as the basis for a new exit signal.

To specify a custom exit

Select Custom.
Enter a name for the Custom exit.
Click the OK button.
Enter a formula for the signal on the Signal tab, using the Formula Toolbox.

To specify a money management exit signal

The Money Management exit type enters a stop order at a price that represents the maximum you are willing to lose per trade.

Select Money management.
Enter a Name for the signal.
Enter an Amount representing the maximum acceptable loss per trade.
Click OK to apply the selection and close the New Exit window.

To specify a break even exit signal

A Break Even exit signal allows you to specify a certain price level for the stop to activate. Once the profit level is reached, a stop order is placed at the entry price. Therefore, the trade will break even, if the stop price is hit.

Select Break Even.
Enter a Name for the Break Even signal.
Enter a Floor price.

The Floor price represents the point where the stop order takes effect.

To specify a trailing dollar risk exit signal

A trailing dollar risk stop allows you to specify a profit level that is no less than a user-specified dollar amount below your highest profit. In other words, it represents an amount you are willing to "give back". As profits rise, the stop will also rise.

Select Dollar Risk Trailing.
Enter a Name for the Dollar Risk Trailing signal.
Enter an Amount.

The Amount represents the "give back" amount.

To specify a trailing percent risk exit signal

The trailing percent risk option allows you to specify a minimum level of profits and a retracement level. In the above example, the stop would activate once profits had reached $2000, and the stop would be set at 50% of that level, i.e. $1000.

Select Percent Risk Trailing.
Enter a Name for the Percent Risk Trailing signal.
Enter a Floor amount.
The Floor amount represents the level of profits where the stop is activated.
Enter a Percent.

The Percent value represents the percentage of the floor value where the stop is placed.

To specify a profit target exit signal

The Profit target option sets the stop at the price that represents the designated profit amount.

Select profit target.
Enter a name for the profit target signal.
Enter an amount.

The Amount represents the profit goal.

To specify an entry stop exit signal

Unlike the other exit rules, the Entry Stop option sets the stop using a bar value.

The Entry Stop enters the formula "BarsSinceEntry(@,0,All,ThisTradeOnly)" as an exit. If you choose High, then the next bar's high (or whatever number of bar's out chosen) is used. If you choose Low, then the next bar's low (or whatever number of bar's out chosen) is used.

Select entry stop.
Select High or Low.

48.Designating the Exit Price

Click the Price tab.
Designate the price (using the Formula Toolbox) to be used for the exit signal.

A price can only be designated when either a Stop or a Limit order has been designated as the order type, since Open and Close already refer to a specific price.

49.Designating a Size

Click the Size tab.
Input the quantity for each trade.

Specifying Trading Costs

The Costs tab allows users to enter a commission amount, thereby providing a more accurate reflection of a system's profitability.

To enter a commission amount:

Click the Costs tab.
Enter a commission amount.
Select either fixed or per contract from the drop down list.

50.To display a trade system on a chart

CQG considers the trade system a study. So like a study, we can:

a) Create, at first, the trade system button in the study window, close this window and then left click on the button appearing on the screen.

b) Add study window; right click on the chart, select Add Study. The window below will come up: Trade system is placed at the bottom of the list. You need to select which one you have to plot on the chart and click on add button.

The graph shows the results of implementing this trade system. It reports a great profit profile. Unfortunately, it doesn't work like that in reality.

$c:\users\sophiaj\appdata\local\temp\snaghtmlb8aa97a7.png$

Click the in Display column.

$c:\users\sophiaj\appdata\local\temp\snaghtmlb8ac6d9b.png$

The following window will appear.

$c:\users\sophiaj\appdata\local\temp\snaghtmlb8ada34b.png$

Click the Trades in Trades column.

The following window will display. You can check the check boxes to display on the chart your Entry Stop/Limit and Exit Stop/Limit.

$c:\users\sophiaj\appdata\local\temp\snaghtml1340082.png$

To edit Bar Range & Changing Trade Colors

Click the in TimeRange column to edit Bar Range & Changing Trade Colors.

To chart signals

Trades can be identified by:

Up/down arrows showing the opening of the trade

Horizontal Lines linking the opening price with the exit bar

Crosses showing the exit bar

Ovals standing for the exiting price

Dashed line showing the entries - exits limit / stop orders

To export trade system results

There are two different kinds of information you can export or print, when the trade system is applied on the chart:

Trade systems statistics per bar taking as reference point the total net profit values.

Analysis of Closed trades, taking as reference the Closed Net Profit value. In this analysis you will see how many trade have been opened and closed; which type of exit has been used; the entry and exit price; time etc

Tools are as follows.

Tabular display:

Tabular trades :

You can call up one of these at a time with a right-click on the printer button (on the top left of CQG screen).

CQG also allows you to export your results to a Microsoft Excel spreadsheet:

Right-click the Printer button.
Select Tabular Display.
Highlight all the data in the table and then press CTRL + C to copy the data into the clipboard.
Open a spreadsheet.
Press CTRL + V to paste the data into the spreadsheet.

Inserting Functions into Entry and Exit Signals

The CQG Trade system feature comes with several special functions, which can be used to create entry and exit signals. These functions are only accessible from the Formula Toolbox using the Trade System tab in Formula Builder.

Establishing Security Provisions for a Trade system

The CQG pacs and components feature allows users to create security provisions that preclude unauthorized persons from accessing a trade system.

51.Trade System Studies

52.Trade System Samples

CQG provides two trade system samples for you: cqg.AMASamp and cqg.StochSample.

cqg.AMASamp Signal

AMA(@,ERPeriod,FastPeriod,SlowPeriod)[-1] XABOVE MA(@,Sim,MAPeriod)[-1]

The signal becomes true and initiates a long entry when yesterday’s Adaptive Moving Average crosses over the Simple Moving Average from yesterday.

Parameters have been configured for the studies AMA (ERPeriod, FastPeriod, SlowPeriod) and MA (MAPeriod). The parameters make changing the associated periods easier from the chart window. These parameters are available for the entire trade system, so they may be used in both entries AND exits.

To change the values for these parameters, right-click on the trade system as it is displayed on the chart and select "Modify..." The parameter names will appear as column headers and the values will be found under those headers.

The Order type for this Entry is a Market Order. This means that the Trade will be executed at the Price specified in the Price tab when the Signal is true. The other order types include Stop, Limit and S/L (Stop/Limit).

The Allow multiple entries before exit (Pyramids) is fairly self-explanatory--it allows additional entry trades to be placed if the condition for that entry is hit before the exit condition is met.

The Allow entry on exit allows an entry to be placed on the same bar that is an exit for a previous trade(s). This is especially useful for Stop-and-Reverse systems.

cqg.AMASamp Price

Open(@): The price used for the trade is today’s open as the signal happened yesterday.

cqg.AMASamp Size

In this sample, the trade system trades 7 contracts. This field could also be a formula evaluating the number of contracts based on market conditions.

cqg.StochSample Signal

B.cqg.StochXAbove(@,XUpThreshold,SSKPeriod)

This System relies on the condition cqg.StochXAbove and cqg.StochXBelow. It is a reverse type system. That is, when it exits a long it also enters a Short and vice-versa. The Threshold values and SSK Period are parameters that may be optimized.

The orders in this system are all signal based.

cqg.StochSample Price: Close(@)

cqg.StochSample Size: 1

53.Trade System Functions

Most trade system functions allow you to specify which trades should be included in calculation, as a trade system may have multiple trades. Possible values are:

All Trades = total of the corresponding values of all trade system’s trades

Long Trades = total of the corresponding values for trades that are set to Use as Long

Short Trades = total of the corresponding values for trades that are set to Use as Short

This Trade Only = this specific trade only

Specific trade name = a specific trade, identified by name

For example, consider a trade system that has 6 trades with these open position entry sizes:

Trade Name

Use As

OpenPositionEntrySize(@, ThisTradeOnly)

L1

Long

3

L2

Long

6

L3

Long

7

S1

Short

-4

S2

Short

-9

S3

Short

-5

OpenPositionEntrySize(@, All Trades) = 3 + 6 + 7 - 4 - 9 - 5 = -2

OpenPositionEntrySize(@, Long) = 3 + 6 + 7 = 16

OpenPositionEntrySize(@, Short) = -4 - 9 - 5 = -18
