Looking for general suggestions to speed up the code

[Deleted] 2020.12.18 01:03

Hi, I just started learning MQL5 language, after studying some of the samples in the Codebase, I decided to write a Turtle trading strategy to practice the newly learnt knowledges. I successfully completed the EA and confirmed the results through backtesting, however I found the process of backtesting took long, as the code is nowhere near polished for smooth and fast execution.

Would anyone like to give some general suggestions on how to speed up the code? Thank you very much.

The code logic is to:

Entry at 20 days High/Low with a Buy/Sell order, with 2 ATR stoploss. This position size is adjusted so it will cost 2% of overall loss in the account.
When a first position is opened, as market continue extend for every 0.5 ATR, I add another position size equal to the original one, then move stoploss for all positions to 2 ATR away from the latest opened position. This process will repeat maximum 3 times (open additional 3 positions in total, on top of the original position).
If the 10 days Low/High is higher than the Buy/Sell stoplosses, move the stoploss to the 10 days Low/High, until all positions stop out.

Hi I have managed to solve the problem by combining some codes into void xxx() functions. Also I create my own data structure to contain the messy loop counting parameters, the code is now running smoothly/
