> 1] The "min_profit" in acceptance criteria is NetProfit in EA Studio right, net of all spread, swaps and commissions?

Correct! The "min-profit" includes all swaps, spreads and commissions charged during the trading period.

> 2] What does "optimize_protections" mean in Optimizer,

When the "optimize_protections" option is enabled, the Optimizer optimizes the SL and the TP also.

Mr. Popov would like to give you one. Idea
What do you think about putting a switch to optimize the indicators and another to optimize only the TP and stop

It would be very useful for strategy that comes out in the exit indicator to come out only in TP and sl

Mr Popov, while generating strategies, I'm getting a lot of useless strategies with average position length less than 10. This is even after taking transaction costs into account. If you could add the following setting to acceptance criteria of Express Generator, it would be very helpful:-

1] "min_average_position_length"
2] "max_average_position_length"

Thanks
