he's using pending orders (buy/sell limits).
the pending orders are 5 micro pips apart.
the stop loss is 12 pips.
the take profit is 10 pips.
he has it so when the buy/sell limits are triggered, he can close and restart the script as soon as it goes in profit.
this strategy is only used on Eur pairs.
it's also used between 1:20-2:00 mt4 time everyday.
I'm not sure how many pips above the initial price the pending orders are set, but it's not many, judging by the videos.
it looks very promising. I've watch him/her take a $5000 account to $600,000 in a little over 100 days.
