Sorry, but I still miss the point - If you don't have SL, so when to close losing order.

Let's try to make it step by step and pls without pending orders as they make the mess and hide the truth:
1. Open 1 lot long and 1 lot short with 20 TP without SL
2. Market goes down. Short closes by TP, which means we got level 2.
3. Open 1 lot short, open second long but with doubled lot - 2 and TP 20 and fix TP for first long to the same level as second long.

Am I right? If so, it does make sense.
I'll fix the EA shortly. But I don't beleive it will not change the general strategy risk and profitability.
