Chart Drawing Ask Line on Tester MT5


Hi, when running the tester the chart insisde the tester screen

draws a historic line joining the ask prices.

Cannot explain what is drawing it.

I made sure I saved a template for "tester" with no indicators on it so that the tester starts

a clean chart with nothing other than what the EA draws.

The EA code does not draw any such line.

Also checked on Stategy Tester Visualization: Charts->Properties->Unchecked "Show ask price line".

Any ideas?

Thank you in advance.
