Missing Trading Markers and error in Backtester

 
Hi,

I experience a problem with missing BUY and SELL triangles when I run the backtester a second or more times. The first time the BUY, SELL and Exit triangles are visible, but on subsequent backtester runs only the exit triangles and the profit/loss lines are visible.

I experience this on version 207 as well as 210.

A colleque trader can't even run it a second time, or the platform returns a critical error and will close down.

Does anyone have experienced the same problem? and what have you done to overcome it.

Many thanks in advance for your reply.

Regards, and happy trading/programming.

Ronald.
