Just my opinion but running 1 lot on a $1000 account is probably risking a margin call at some stage…..  That is on a 1:200 broker I guess if you have 1:400 might be more room to move.  I was running this size on demos lately and margin % got down to 300% so a little to low for my liking.  Like to keep my margin % at 500% +.  I feel more comfortable at .5 per $1000 and that is while I am still on small accounts as they get bigger I would drop that further…..
