1 - The max number of open positions is 2. This EA uses emergency stop loss. It's 200 pips from the first position. The second position stop loss is not 200 pips. Let say the EA open a buy position with 10 pips TP and 200 pips SL and the market goes against the trade in about 100 pips and the EA opens another trade with the same stop loss price as the first position and close both positions in profit or SL point.
