I found the problem, the "Trade History" menu on MT5 is causing slow loading.
Turn it off will Solve the slow problem.

I have both buy & sell
ex buy 0.01 0.05, sell 0.03, 0.1
When price go down, I just want to trailing all buy/sell positions when total sum get profit not only winning side. When price reverse to the trailing stop, all positions close

@jstap How do I combine them into 1 position and trailing when profit by using foreach trade ?

Does Trailing Group of Trades work with Buy and Sell sum as one Position ? How to do that ?
I have multiple positions for buy sell with multiple lots size (not equal)
In the picture, if price go down I want to trailing sum profit in pips on all positions (like trail money on loss function buy I want it as pips)

I have tried Trailing stop (group of trades) block. But it do only trailing on profit side (trailing only sells when price go down) I want it to close both buy and sell positions when trailing reach. like sum of position.
How can I do that ?

It happen to all projects when load to this pair XAUUSD (has many history positions), including a simple project from the shared link. But on EURUSD (has a few history orders), it works fine.

You can try loading EA on this Demo account:
MT5

Demo2024!
Eightcap-Demo

I have noticed that the speed when loading EA on MT5 is taking a long time to load, around 30 seconds to complete, On this pair that has 5000+ history orders.
Compared to the other pair with no or less history orders, it load within a second.
(*This EA did not use any blocks 'Bucket of Closed Positions' or 'For Each Closed Position')

I have tried with many EAs from MA Cross Logic to a Simple Show current time Message.
All took times to load complete of the pair that only have many history orders.
