Indicators not signaling Buy/Sell.

Griffin Mahoney 2024.03.01 16:47

So I'm pretty new to MQL5 and Metatrader in general but I wanted to build my own EA with simple moving average and stochastic crossover. I feel as though I have the code right but when run in the strategy tester it places no orders, even when the conditions to do so are seemingly met in the data. Is there anything super obvious I'm missing? Thanks in advance!

The Fundamentals of Testing in MetaTrader 5

www.mql5.com

What are the differences between the three modes of testing in MetaTrader 5, and what should be particularly looked for? How does the testing of an EA, trading simultaneously on multiple instruments, take place? When and how are the indicator values calculated during testing, and how are the events handled? How to synchronize the bars from different instruments during testing in an "open prices only" mode? This article aims to provide answers to these and many other questions.

These functions return the indicator handle, not the buffer values.

Most likely, you generated this code using artificial intelligence. Artificial intelligence harms MQL learning because it generates complete nonsense. Don't use artificial intelligence when learning MQL

Thank you I do see what I did wrong there. I didn't use AI but I have been extensively youtube/googling and I guess you're bound to end up with something ridiculous at some point.

That being said I did update my code using CopyBuffer but still no orders being placed.

[EDIT]

You are copying 0 values because the sizes of the arrays are zero
