Happy New Year everybody !!


Hi experts,I have a question about how to code following trading condition.


rule

1.Fast moving average cross up slow moving average

2.If RSI >70 within 50 bars after crossing  then open long


It mean 50 bars after cross up ,just wait for RSI>70 but won't be under first condition .

I think that loop (for,while) must be used  but I confuse in this case.


thank very much

 
Just use if...else statement

Before you start trying to re-event the wheel - there is practically nothing that does not exist for mt4/5. Start searching (top right) or googleing!

The best way to learn coding is quite simple: Just take an existing EA or indicator and change it according to your goal.

1 more question.


How to set any variable to index like timeseries?  or return value of variable by shift. 

such as

If(condition1 and condition2 and condition3 ........)

x=1;

when time passes,how we get value of x ?

 

Just read in the reference (editor->F1) about iCustom() and or iRSI() and then try to understand how it is used in a working EA from the CodeBase.

With 'shift' > 0 you can look into the past, 0 will give you the actual value.

Obviously are are still very much a beginner at any type of coding, so any explanation we give you here is probably not going to be easily understood.

So, I suggest you first learn the basics and the following book can help you learn the necessary skills:
