Working Strategy

If there are no open positions (opened by the EA), two oppositely directed positions with the "Lots" initial lot are opened with a stop loss equal to "Stop Loss", while take profit is not used. Stop loss moves using trailing ("Trailing Stop" and "Trailing Step" parameters are applied).

Trailing

Position's first modification reliably moves a stop loss to a breakeven or even a small profit. The subsequent modifications of Stop Loss increase the guaranteed profit.

Two stop loss activation options are available afterwards:

• 1. Position has closed with a loss
• 1.1. In this case, we assume that the trend has reversed. Open a position with an increased lot (add "Number of minimum lots" to the volume of the remaining position) in the direction opposite to the closed one. For example, the unprofitable BUY position has been closed. Then open a SELL position with an increased lot. Thus, we obtain two positions in one direction.
• 1.2. Further on, it works only in the obtained direction: wait till the price leaves the least loss-making position by "Step" points in the loss-making direction and open a position with an increased lot (add "Number of minimum lots" to the volume of the least loss-making position) in the direction of existing positions (as you remember, we have one or several unidirectional positions).
• 2. Position has closed with a profit (this is the position that was modified at least once)
• 2.1. We assume that this is not a trend reversal, but a small rebound. Open a position with an increased lot in the direction of the closed one. For example, a profitable BUY position has been closed, then we open a BUY order with an increased lot. Thus, we obtain two positions in the same direction.
• 2.2. We try to apply trailing afterwards. In any case, one of the Stop Losses will work and we will return either to p. 1 or to p. 2.

Calculation of BUY and SELL positions, total profit on BUY and total profit on SELL, as well as searching for the least loss-making BUY and SELL position are performed within one call in the CalculateAllPositions function.
