Working code.

Hello.

I have decided to learn MQL5, I have read articles about how to generate EAs in MetaEditor, everything is clear but how to make indicators that are part of EAs to trade by your rules, for example CCI indicator does not do what I want; how to make a buy order open at crossing 100 and close it at the crossing 100 from upside down; the same for sell. I have also been working on this for a while now and I dont know how to do it.

I have a distracted question. How do you use MQL4?

[Виктор Гринько]

no way

no way

then safely forget about the code generator.

Open a standard example from the delivery of MA or MACD

Change the indicator to CCI

and go

Hello!

Sorry for the, in my opinion, stupid question:

I wrote an EA on mql5, loaded it properly, tested it, tried it on a demo on my home laptop and now the demo is running on VPS.

I uninstalled it from my laptop. Tweaked something on the source on VPS.

Tried to load from VPS to laptop - does not see it MQL5!!! W7 Explorer has it where it should be, but MQL5 has not.

Metaeditor via Open file finds, edits and saves it.

When I try to compile it, the error cannot create interface of MQL compiler in the first line. What is this error?

What do I do?

Could you please advise how to get the current price in the indicator code and compare it with another indicator to draw a line?

I get the current price in the Expert Advisor:

MqlTick latest_price;       
double iclose=latest_price.bid;

But how do I get it in the indicator?

In the EA I get the current price as follows:

But how do I get it in the indicator?

Look in the code of indicator, function OnCalculate().
