The tester does not report any errors, just no orders are placed.

Please, point out the error, the logic: if the value of MA [0] of the bar is higher than MA [1] you have to buy, on the contrary - sell (this code was written as an example to try to understand a simple condition and create a more complicated one).


This code does not use MA[0] and MA[1] but MA[j] and MA[j+1];

After a small revision of the code (very small), error 4107 appeared

I can make it work, but it will be a totally different EA. I am simplifying it to the maximum. And here the code can be more than halved.

If Stops and Takeovers are set equal to zero, the Expert Advisor starts to open trades

 
Vinin: I can make it work, but it will be a completely different EA. I am simplifying it as much as possible. And here the code can be reduced by more than half.
Vinin, if you can make it work with closing at stop or take profit, the main thing for me is to feel the philosophy of mql in addressing different bars in the array.
 
Good evening! The MQL4 indicators are not working when I pull them onto the chart, but nothing at all! Please help!

The thing is, advisors work and indicators do not work at all!

I have checked it. It works. The signal is a change of direction

Nice, but how does it work in code (logic): If MA150+20 > MA5 > MA150-20 and MA150+20 > MA21 > MA150-20 Then flat else Trend.
The logic is somewhere around here... I made it fast, so sorry, if anything...

I want to use Ramus volumes in MT4, they seem to have more realistic volumes.


 
IgorM:


my system is set up to always want to open an order and I limit it by forbidding signals, only signals give me permission to trade = order

I have a small problem now - there are no late trades, but there are problems with random orders in the night flat - so far I dream of teaching the EA to distinguish the flat, and not limiting it to the time of day to work. For the estimation of the trend I am using higher TF in the EA logic, so I am able to put it at night on an hourly TF and it seems to be less stubborn than on M15

Why restrict? You may use separate strategies for trend and flat. Let it always work, as long as it works ... ;)
 
Thank you, Vinin, thank you, artmedia70.

How do I use object crate and object set to draw a horizontal line in a stochastic window, for example?
