Thank you.

I wrote Print("Bar count on the 'EURUSD,M1' is ",iBars("EURUSD",PERIOD_M1));, taken from the documentation. I printed the number 1001 in the log.))) Although, the history is loaded, the max is more than 1000000 bars in the settings.

Please advise how to solve the problem

Thank you.

I wrote Print("Bar count on the 'EURUSD,M1' is ",iBars("EURUSD",PERIOD_M1));, took it from the documentation. The terminal logged the number 1001.) Although, the history is loaded, the max is more than 1000000 bars in the settings.

Please advise how to solve the problem

in the tester always 1000 bars at start (or less).

This code shows the signal on the 10th candle, but I need to check the signal on each candle from 1 to N.

No, this code checks 10 candlesticks and shows which one was the signal

In practice it only shows when the signal candle becomes the 10th.

MakarFX, here is a screenshot As soon as the signal candle became the 10th, the value was greater than zero. And before that it was equal to zero.
