This high risk Special formula Zone Recovery EA is an advanced hedging system. When the market goes against you by certain number of pips, you open an opposite trade by a trade with slightly bigger lot size.
If the market keeps moving in this new direction, at some point the profit from the profit trade will overtake the loss trade, at which point you can close both the trades.
If the market returns to the previous direction, the trade with the bigger lot size will accumulate loss faster than the older trade which is gaining. In this situation, calculate and open another trade in that direction by which the initial trade and the third trade together will be bigger than the second trade.
This back and forth hedging strategy can be continued for 6 iterations until the market moves to a level which can give profit or break even.
