Alexandr Sokolov:

I had an idea, I need a lot of cycles, so I decided to check the speed this way

... As a result MT5 stops working, glitches and I have to close it via task manager


Is this a problem in the power of my pc or something else?


*PS - I want to try to write a neural network, and there will be billions of cycles, and here I'm going by a million.

But I caught it twice without any glitches, but if I repeat it again it glitches (script in attached files)

don't try it :-)

or rather, write something simpler first

Because the problem is in the lack of understanding of what you're writing and how it works in general.

This script is not a neural network)) I made it to see how fast a million cycles go by


But why is the terminal glitchy? The script starts working (digits are running), but I don't get to the end (at least for me)

 
Good afternoon, gentlemen programmers. Please advise. I am trying to write an arrow indicator based on reversal patterns and others. It seems to be OK. However, it only considers the first 2 candlesticks instead of 4. When compiling, the editor swears about possible loss of accuracy when assigning different data types. And only on iVolume. Thanks in advance.

Here is the code for the indicator.

Вот код индикатора.

The problem is that as you can see on the chart, the volume of 3 candles from the buy signal is 3 points. But in the code the volume is prescribed from 8 and above.

In the future, I want to attach a mailing or sms. I tried to write an EA with MACD, MA, and RSI indicators using this principle. There are few false signals. But I would like to control the process myself.

I used harami, two candle absorption, hammer, gap and veil, counterattack patterns as the basis.
