소개

The exp_iCustom Expert Advisor is designed to trade on custom indicator signals. To configure the expert to use the indicator, no programming skills are required; all settings are made through the expert properties window: the indicator name, a list of parameters, and indicator buffer numbers are entered.

Types of Indicators Used

An expert can work with the following types of custom indicators:

1. The indicator draws arrows (icons) for buy / sell. The EA opens orders on these arrows (Fig. 1).

2. The indicator draws two lines, we will call them the main and the signal. The EA opens orders at the intersection of these lines (Fig. 2).

3. The indicator draws one line. The EA opens orders when a line crosses certain levels (Fig. 3).

4. The indicator draws one line. The EA opens orders at extreme points of this line. The extremum is determined by three bars (Fig. 4).

Fig. 4. The indicator draws one line. Orders open at three-bar extremes

5. The indicator draws a multi-colored line. The EA opens orders at the beginning of a new color section. In this mode, not all multi-colored indicators can be used (Fig. 5).

6. The color change when crossing through 0. Typically, such indicators draw histograms in the subwindow; for values ​​above zero, the histogram has one color, and for values ​​below zero, another (Fig. 6).

Inappropriate indicators

1. Indicators having string parameters. You can check if the indicator has string parameters by looking at the “Input parameters” tab of the indicator properties window. String parameters are marked with the icon with the letters “ab” (Fig. 7).

2. Indicators using graphic objects for drawing. To check whether the indicator draws icons and lines using indicator buffers or graphic objects, you can try to select the icon (or line) by double-clicking. If an icon or line can be selected and moved, it means they are drawn using graphic objects (Fig. 8, 9).

Fig. 8. Arrows from graphic objects. An object can be selected by double-clicking on it with the mouse and moving, unlike the arrows drawn using indicator buffers

Fig. 9. A channel from graphic objects “trend line”. The line can be selected by double-clicking on it with the mouse and moving, unlike the line drawn with the indicator buffer

3. Some multi-colored indicators.

There are indicators using various methods of coloring. If one line always matters, and the second line periodically has or does not matter, such an indicator cannot be used. To find out which coloring method is used in the indicator, you can increase the thickness of the bottom line and see if it always exists or disappears (Fig. 10).

Fig. 10. Two-color indicator with an increased (for clarity) the thickness of the red line. It can be seen that the red line always matters

Expert setup

An expert can use three custom indicators: an indicator for opening orders, an indicator for closing orders and an indicator for trailing. Accordingly, in the properties window there are three sections of the same type of parameters. Parameters of the section for opening orders begin with the prefix “_O_”, the parameters of the closing section with the prefix “_C_”, the parameters of the section for trailing with the prefix “_TR_".

단계 1

The indicator name is entered into the iCustomName variable. The indicator name corresponds to the indicator file name without extension. To avoid mistakes, when entering the name of the indicators, it is best to copy it using the mouse - find the required indicator in the MQL4 / Indicators directory, right-click on it, select the “Rename” command, and the indicator name should highlight, then click again right-click and select the copy command (Fig. 11).

Fig. 11. Copying the indicator name to the clipboard

After copying the indicator name to the clipboard, you should open the indicator properties window - double-click on the value input field to the right of the _O_iCustomName variable, then right-click again and select the “Paste” command (Fig. 12), then delete the extension and the point.

단계 2

A list of indicator parameters is entered into the _O_iCustomParam variable through the separator “/” (Fig. 13).

Fig 13. Indicator parameters in the _O_iCustomParam variable.

If the indicator has a variable of type datetime (in the properties window the variable has a clock icon), you must specify the type of the variable “date:”, 예를 들어:

15 / date: 2011.10.17 16: 36/30.

Similarly with variables of type color (in the properties window the variable has an icon with a yellow-orange rectangle), you must specify the type of the variable “color:”, 예를 들어:

15 / color: Red / 30.

단계 3

The _O_Mode variable indicates the type of indicator signals used, the s0 variable contains a hint for possible values: 1 - 화살, 2 - main and signal, 3 - line and levels, 4 - extremum, 5 - color change

단계 4

Indication of indicator buffer indices. Each type of signal has its own variables, in which buffer indices are indicated. When working in the _O_Mode = 1 mode, the variables O_M1_iBuyBufIndex (the index of the buffer with buy arrows) and _O_M1_iSellBufIndex (the index of the buffer with sell arrows) are used in the mode _O_M2_iMainBufIndex (the main line buffer index) and _OalBuilder 3 - _O_M3_iBufIndex (line buffer index), in this mode, the variables _O_M3_BuyLevel and _O_M3_SellLevel indicate the values ​​of the levels at the intersection of which the order is opened. When the level _O_M3_BuyLevel is crossed from bottom to top, a buy order is opened, and when the level _O_M3_SellLevel is crossed from top to bottom, a sell order is opened. In mode 4, the variable _O_M4_iBufIndex (index of the line buffer) is used; in mode 5, _O_M5_iBuyBufIndex (index of the line buffer displayed when trending up) and _O_M5_iSellBufIndex (index of the buffer of the line displayed when trending down). The indicator buffer index can be determined from the “Colors of the indicator properties window” tab, the buffer index is indicated in the “No.” column (Fig. 14).

Fig. 14. The buffer index is indicated in the column “No.”

If there are several buffers of the same color in the “Colors” tab, change the color of one buffer to a color different from all the colors, close the properties window and see if the desired buffer has changed color. 따라서, you can determine the index of the desired buffer.

At this step, the main settings of the expert can be considered complete.

단계 5

Setting methods for closing orders. The choice of closing method is performed by the _OC_Mode variable, possible values: 1 - closing only by stop loss and take profit, 2 - orders are closed by the signals of the opening of the opposite order, 3 - signals of the additional indicator are used (variables starting with the prefix “_C_”)

When using the _OC_Mode = 1 mode, it is necessary to set the required stop loss and take profit values ​​in the StopLoss and TakeProfit variables. Stoplos and take-profit can also be used in all other closing modes, or you can disable stop-loss and take-profit, enter 0 to disable it. When using mode 3, you need to configure the variable section with the prefix “_С_”, the settings are the same as the settings of the variable section with the prefix “_O_” (steps 1-4).

When choosing the closure type 2 그리고 3, you can use additional closure rules - the variables CheckProfit, MinimalProfit, CheckSL, MinimalSLProfit. When you enable CheckProfit, before closing, the profit of the order is checked; if the profit of the order is less than MinimalProfit, the order is not closed. When you enable CheckSL before closing, the position of the stop loss order is checked, if the stop loss fixes MinimalSLProfit or more profit points, then the order is not closed.

단계 6

Selection of the type of orders used. An expert can work with market orders or pending. The type of orders is selected by the OrdType variable: 0 - 시장, 1 - stop, 2 - limit. When choosing type 0 (market orders), the Slippage variable indicates the permissible deviation from the requested price (the parameter corresponds to the parameter located at the very bottom of the order opening window (Fig. 15)).

Fig. 15. Slippage parameter in the order opening window

When using types 1 그리고 2 (pending orders), the variables PendLevel, PendPromPrice, PendNewSigMode, PendPriceFollow, PendDelete, PendExpiration are used. In the PendLevel variable, the level of placing pending orders from the price is determined, measured in points. The PendPromPrice variable determines the price from which the level of placing pending orders is calculated: 0 - from the current price, 1 - from the bar opening price. In the PendNewSigMode variable, the way to control a pending order by a new trading signal is defined: 0 - if the order has already been set, then no actions are performed when a new trading signal appears, 1 - reinstalling the order with a new signal, 2 - with the new signal, the order is reset only to “Best level” - by-stop only down, buy-limit only up, sell-stop only up, sell-only just down. The PendPriceFollow variable enables the “follow the price” mode - the order is pulled up after the price changes (trailing pending orders). PendDelete - deletion of a pending order by the opposite trading signal, if false, two orders of different directions may exist simultaneously. The PendExpiration variable sets the lifetime of a pending order, measured in minutes, the minimum value is 11 분.

단계 7

Setting support for open orders. The EA has trailing, 손익분기점, indicator trailing functions.

Trailing is enabled by the variable TrailingStop_Use - if true, trailing is used, if false, disabled. The TrailingStopStart variable determines the profit of the order (in points) at which the stop loss starts to move. The TrailingStop variable determines the stop loss level (in points) from the current market price.

Break-even activation is performed by the BreakEven_Use variable - if true, break-even is used, if false, BreakEvenStart variable determines the profit of the order (in points) at which the breakeven is triggered. The BreakEvenLevel variable determines the level (in points) at which the stop loss is set from the breakeven price, BreakEvenStart-BreakEvenLevel profit points are fixed.

Trailing by the indicator is configured in the variable section with the prefix “_TR_”, the setting is similar to the setting of the opening section (step 1-4) - the indicator name, parameters are entered, the indicator buffer indexes are indicated - variables _TS_iForBuyBufIndex (buffer index for buy orders) and _TS_iForSellBufIndex (index buffers for sell orders). 추가적으로, the _TS_Indent parameter determines the indent in points from the value of the indicator line at which the stop loss is set and the _TS_TrailInProfit parameter enables the mode in which the trailing starts working only if the stop loss is set to the profitable level for the order.

단계 8

Selection of the type of order volume control. Three modes are possible: a fixed lot, a percentage of a deposit and a percentage of a normalized deposit. The type is set by the MMMethod variable: 0 - 고정 로트 (Lots variable), 1 - part (위험) of free margin, 2 - part (위험) of free margin normalized by MeansStep value, for example Risk = 0.1, MeansStep = 1000, if less 2000, the lot is 0.1, if the funds became 2000 또는 그 이상 - 0.2 lots, 3000 그리고 더 - 0.3 lots, 등. The MeansType variable determines the type of funds used in calculating the lot size. 1 - Balance, 2 - 형평성, 3 - FreeMargin. The LotsDigits variable determines the number of decimal places at the lot size 1 - one decimal place (lots of type 0.1, 0.2 ...), 2 - two decimal places (lots of type 0.01, 0.02 ...), 등.

단계 9

Setting the maximum number of open orders. The MaxOrdersCount variable determines the total allowable number of open buy and sell orders, with a value of -1 the total number of orders is unlimited, MaxBuyCount - the allowable number of buy orders (with a value of -1 - unlimited), MaxSellCount - sell orders (with a value of -1 - unlimited )

Expert Optimization

Indicator parameters are entered into a string variable, which does not allow optimization in the usual way, but the expert has the opportunity to optimize up to 5 indicator parameters; for this, in each section of indicator variables (“_O _”, ”_ C_”, “_TR_”) there are subsections of variables “Opt” - in each section, 5 variables Opt_X_Use, Opt_X_Index, _O_Opt_X_Value. The Opt_X_Use variable enables the use of the corresponding Opt_X_Index and _O_Opt_1_Value variables. The Opt_X_Index variable indicates the number (counting from 0) of the indicator parameter for which the value of the _O_Opt_1_Value variable is used (Fig. 16), and the value entered in the parameter line is ignored.

Fig. 16. Use of the “Opt” Variables. Instead of the values ​​5 and 34 of the parameters entered in the line at positions 0 그리고 4, the values ​​from the variables _O_Opt_1_Value and _O_Opt_2_Value will be used

Indicators with listings

For some indicators, external parameters can be set using enumerations, 이 경우, in the indicator properties window, there is no field for entering the variable value, instead there is a drop-down list for choosing an option, such as in the 2MACross indicator (Fig. 17).

Fig. 17. Drop-down list - listing

When entering the indicator parameters into the _O_iCustomParam variable (and other similar variables), it is necessary to indicate a numerical value corresponding to some specific list item. In order to find out which number corresponds to the selected list item, you need to attach the indicator to the chart, set the necessary parameters for it and save the template. To save the template, right-click on the chart and select: Template - Save Template. Open the saved template in notepad (for this you can open the notepad and drag the template file onto it), find the indicator parameters and look at the values ​​(Fig. 18).

Fig. 18. Template file in notepad

As you can see from the image, the “Median price” option was selected for the FastMAPrice parameter, the value is 4. It means in the line _O_iCustomParam we enter: 5/0/4/0/34/0/0/0.

All expert parameters
