Understood about BP...
Regarding the error message: I tried messing around with all types of "Round" and it doesn't work. But even if it worked, in your example would be perfect for prices with 3 decimals. But if I would use the same script for 0.0022 Bid and 0.0023 Ask, I would be screwed. It would be great if there was a function of "Round" to round always the last decimal ( NOT "Round2", "Round3", "Round4", etc.), so I don't have to make a lot of hotkeys differentiated by decimals. I was wondering maybe there is an easier solution to that or maybe there is a bug I should sort. Anyway... Thank You for your contribution Peter... Much appreciated...
