Problems with short-only trading systems

[Charlie]

If I copy a trading system, edit it to create the conditions for selling short, and then save it, the backtester won't let me select it. I used to be able to select it.

Also, I can't get the TRIX system to work in the current version (2022/04/22). The earlier version had a  problem with TRIX as well. But I was able to correct the coding and now don't remember what I did.

Hi Charlie,
In back testing, short selling is not yet supported. I am hopeful that this feature will be available soon.
Regarding TRIX system, I see there is a problem with it's definition. Instead of EMA(9) it should be EMA(9)[TRIX], basically cross over of TRIX with its EMA should be used. I will fix this and update soon.

Sacha,

Much thanks for your quick reply.  I really appreciate the care and concern you have to make SA the best it can be.
