4109 Bug in reverse script

[pc-wiz]

I just coded a little script to use with a single position per pair; it should just kill what's there and open a new one in the other direction, but I get this "Trade not allowed" - anyone know what causes that? ( Code attached )

Alright I don't much about coding but how exactly is the first position open?

On the Interbank FX platform I open a chart and take a small position. Then I drop the script on it, and I get a 4108. I appreciate you're looking at it.
