Yes

Testing Av02 for 2000 on M5 gave a good loss on both the euro and the pound.

The Av02 test for the year 2000 gave a good loss on both the euro and the pound.

If the average loss per trade is more than two spreads, you can reverse the system and there will be a profit.

Are you talking about Av02 exactly? Because the "trick" you suggest does not work with other EAs - it gives losses too: I checked it more than once.

If the average loss per trade is more than 2 spreads, it works on any EA.

Yes, but the criterion could be a year and the ability to earn a decent wage in that year.

??? The stability period of the system is impossible to guess, it can stop working at any time

paukas:

If the average loss per trade is more than 2 spreads, it's OK.

On Av02 max = 3, 841

[Vladimir Paukas]

volshebnik:
On Av02 no more = 3, 841

There you see. Get a "plum" system just as much as a profitable one.

So the system and its optimisation before that is not working. The purpose of optimisation is to make the system work for the next period. And if in this short period it makes a loss, then it is not suitable.
