Description of the My Stop Loss Expert Advisor:

It transfers the Stop Loss level of any open order to the zero level, plus the specified number of points, when the specified number of points in profit is reached.

• Level Profit - profit level in points, which must be reached by an order to transfer its Stop Loss to the breakeven level.
• Level WLoss - breakeven level in points, at which the Stop Loss of a position will be transferred after its profit reaches the LevelProfit value.
• Magic - numeric identifier of positions: if zero, the EA will monitor the positions with any magic number; otherwise, only the positions with the specified magic number.

All ingenious is simple.
