Hello! How do I connect a custom indicator to an EA as a resource?

#resource "\\Indicators\\indicator.ex4"

[Oleg Kolesov]

Hello Taras! Been working with you. Good to meet you. I connected the indicator to my Expert Advisor as a resource. I am not sure if I did it correctly?

//|[e-mail] |
//+------------------------------------------------------------------+
#resource "\\Indicators\\\KChange.ex4"
#property copyright "Koles"
#property link "https://[e-mail]"
#property version "1.00"
#property strict

int start()

{
H=iCustom(NULL,TF,"::Indicators\\\KChange.ex4",History,Period_1,Period_2,MA_method,0,1);

The compiler has not found any errors, but the tester is working much slower? Is it normal?

//-----------------------------------------------------------------------------------------------------------------

The MQL4 manual says: reference to variables in theinitialization function?

//+------------------------------------------------------------------+

//| Expert initializationfunction|
//+------------------------------------------------------------------+
intOnInit()
{
//--- get the value of the custom indicator
doublevalue=iCustom(_Symbol,_Period,"::Indicators\\\SampleIndicator.ex4",0,0);

Reference to indicator variables in theinitialization function , not in the start function? Please advise experienced people!

Help at the top:"Documentation" is called.

Please refer to "MQL5 Programs --> Resources --> " there see"Working with custom indicators connected as resources".

Everything is clear and simple. And often with examples.

Artem indicator and EA files EX4.

Oleg Kolesov:
Artem indicator and EA files EX4.

The indicator must be inserted into the EA as an executable file (.ex4/.ex5), but if the EA is also an executable file, and there is no source file, then there is no way.

Hello, I would like to write an EA which will place a pending order at every tick. But it will put BuyStop on the first tick and then not put it again. There is an error 130. What is the problem? Please help me.

Artem wrote the indicator and the Expert Advisor himself. Create with MQL4 Wizard an Expert Advisor(template), custom indicator, script, library, include file(mqh), new class? Include files (#include)?

If you wrote it yourself, you have the source code of the Expert Advisor - insert the indicator as a resource into it.

1. The order setting price is not normalised.
2. All prices should be checked against the StopLevel - if the order distance in points from the price is less than the StopLevel value, then there will be an error 130 - wrong stops
