Yes, it’s set too aggressively. Try these settings:
1
2
3
ONCEfactor=8// factor of 10 means margin will increase/decrease @ 10% of strategy profit; factor 20 = 5% etc
ONCEmargin=(close*.05)// tier 1 margin value of 1 contract in instrument currency; change decimal according to available leverage
ONCEmargin2=(close*.05)// tier 2 margin value of 1 contract in instrument currency; change decimal according to available leverage
The margin % is set by IG and .05 should be correct for France. The factor you can optimize yourself to see what works best, but usually 8 or 10 is safe.
