Hi Rob,
I think we share a simaliar style of risk control! I like to cut losses quickly, but not too quickly, that's important for me. Give it room, let it breath, she's a living being... Rob knows all about what I'm saying! ;-) That's the only problem I have with shorter TF's, you have to be super quick with your decision, otherwise price has driven off without you in the backseat (or crashed into your stop)!! I just don't like holding positions overnight... ahh the crazy world of trading!
Have you ever thought about trading Direct Access Rob? I think that would suit you better, assuming you don't already, since the execution is faster and there are no spreads (apparently, never tried it).
Take it easy.
