Kenny,
All valid points. If I get this in order, I'll be using it on Interbank's platform. They've got the whole "we prefer you holding a trade for 90 seconds" thing, but I've talked with their reps before, and the 90 second rule primarily applies to news traders. If you average out the 500+ trades in a session, I'm coming in around 1 Min and 30 seconds per order. They definitely won't have a problem with this scalper.
The real trick for me is not in finding the right broker, its getting this method set up right. I totally agree about having to recoup spreads and what a daunting task it is to clear profits from every few minutes of noise. I swore to myself in the past that this sort of printing press concept is not viable. Like you (from the sound of it) I spent years running number sequences on grid layouts and such. However, I feel that this might be attainable, after all.
I've reworked the numbers and am firing this puppy up next week. Apparently, the weakness for the EA was my desire for excessive gains. I've skinnied down to a point where the profit potential is still of interest. I'll watch it next week to see if the "pain" threshold was lowered.
This is a great time to be testing.
