I wonder ..... what this sign means.... I can't think of anything in the textbook about it.

Transferring by reference, allows you to modify (change) the parameter

The transfer by reference, allows modification (change) of the parameter

Thank you. I'll keep that in mind for the future.

But why doesn't the function work?

I would be grateful if you could point me in the right direction.

I need all code

I need that after the order is closed on a stop the following order opens with the volume equal to volume which was in the LAST closed on a stop

order multiplied by 2

And if the LAST order was closed for any other reason (not a stop) - the position volume should be 0.1

Datetime is the same int.

Thank you very much.

Everything compiles.

But........

- opens a position on EVERY five-minute period (every candle)

- the order volume does not change after the last stop
