Hi there Allen,
I am not claiming you do things wrongly as such, but it could be that you’re doing things the PRT platform does not expect. The example you se below from your own text, which is something that can’t be in my perception. “Close 4 out of .4”, which you seem to do indeed.
Something else, but related, we may wonder whether you can have a fractional position in EUR/USD (which is what you use, right ?) in the first place. To me this feels a bit like “let’s have 0.4 contract of 1.086” which of course can’t be for real. Still, PRT may dig that in one feature (Buy) but reject it in the other (SL).
So on this matter, you’d buy 1000 x 1.086 or possibly 1027 x 1.086, but not something like 0.4 x 1000 x 1.086. Or can we ? … if we can then PRT fails in consistency (see above) but it would be you putting up the “strange act”. … Which is never your fault of course. But anyway, thing “larger”. Nobody will be buying a handful of USDollars from EUR, unless you’re in a physical shop and they allow you to.
As far as I know/recall, the standard contract size for EUR/USD at PRT-IG (it looks like you are using that) is 100000. This with a value of 108600. Seems much, but is no big deal really. If you can buy that with 0.4, then fine. But it feels odd and the SL may not be able to deal with that (does not anticipate it).
Side note : for PRT-IB (IBKR as broker) the contract is always x 1000. Thus you buy 100 and obtain 100000. Minimum with PRT is 20000. Thus 20 contracts. The Exchange just does not deal with less. But this is all different with PRT-IG.
I hope this helps you somewhat ?
Peter
