horizontal lines in main chart

[mdtrader]

how can I draw horizontal lines in the main chart?
I think it can be done with plotting a point at the same pricelevel at every tick but maybe there is a better, easier way to do it?

Thank

Hi Mario
Yes, drawing a line is in fact placing points using Level 1 API. If it limits your performance you may want to use core Level 1.

Hi Andrey,
can you provide a example drawing a line using core Level 1 please?

Thanks
