Hey Pak,
I am so sorry for the late reply.
So, in portfolio EA, you get 3 settings for the protection that are:
Max spread (points): What it does is that you set a limit on the spreads which means for example if you set it at 10 and the spread of the pair is 15, it will not open a trade.
Minimum equity (currency): So, minimum equity means that the trades that are open will close if they reach to that amount that you have set. If let’s say you have a balance of a 1000 and you have set the minimum equity to 850, what it will do is that if you have an open trade and from it is on a loss of 150$, the trade will close automatically and there will not be another trade unless you set it to a lower amount.
Maximum daily loss (currency): It is almost the same as the minimum equity but the difference is that it just close the trades for the day if they reach the amount you have set. Once the next day comes, it will trade again.
Hope this helps!
If you have any other questions, let me know!
Kind Regards,
Nikos
