Thank you!

How do we get out? return(0); gives me an error.

Depending on function type. It's not start() but OnTick(), it's void, so just return;

return;

For comments on Print. if not needed when working.

Thank you! Can you tell me how you can put a time limit on the EA's work in external settings.

I have added this



int start()
{
  if(!isTradeTimeInt(21, 30, 01, 00)) return;
 а в конце кода вот это

Can an EA display an indicator? Alternative to ChartIndicatorAdd in MQL5.


And where can I find an example of an EA that performs calculations based on a custom indicator?

 
Can you please tell me if it is possible to prescribe the angle of slope of the moving average or price intersection with the moving average at a certain angle?

Now they'll start explaining to you that the angle depends on the chart scale and it's impossible to do that...
But if you take not the angle, but only the tangent of that angle, you can do what you want.
 
Please advise if anyone knows.

My Expert Advisor, in int init(), first tests a 1000 bar history, then start(). In the tester this process takes 3-4 seconds, but in real life it takes about 8 minutes.
What can it be related to? How can I make the testing take as much time as in the tester?
