How to explain to the Expert Advisor (standard ma) that we should buy (sell) only at the moment of crossing the averages, and not in general, when ma_1>ma_2. And he constantly buys, he can't stop
You need to remember in the variable that the crossing has already happened, and when it crosses back, rewrite the variable that it has already crossed again. This is variant №1.
Look at the history of transactions, if the last Buy, then wait for the signal to Sell, and then alternate like this, this way is more reliable
You need to remember in the variable that the crossing has already happened, and when it crosses back, rewrite the variable that it has already crossed again. This is variant №1.
Look at the history of trades, if the last Buy, then wait for the signal to Sell, and then alternate in a circle, this way is more reliable
Isn't it complicated to add something to the condition itself?
What's the big deal? It's not hard to work with history, and it's even easier to write the intersection into a variable.

If we are talking about the last MA crossing, trading along the MA is usually easier:
1. control the new bar
2. at the new bar we check the condition:
ma_1[1] >ma_2[1] && ma_1[2]<ma_2[2] - top-down crossover
or ma_1[1]<ma_2[1] && ma_1[2]>ma_2[2] - top-down crossover
if it does not make any difference which MA crosses from above, then both conditions shall be used:

When it comes to the last MA crossing, trading on the MA is usually easier:
1. monitor the new bar
2. At the new bar we check the condition:
ma_1[1] >ma_2[1] && ma_1[2]<ma_2[2] - top-down crossover

Friends, could you please tell me why when optimizing an EA, the \Terminal\tester\logs folder accumulates huge log files of the following content:
2 00:00:01.796 2014.04.01 10:57:30 Tester: #102 deleted due expiration

And some of my EAs write such logs and some don't. I cannot make it out.
How is that possible?
