The Expert Advisor opens an initial position in the current candle’s direction and increases its volume if profit in points increases a threshold fixed in the EA inputs.
The data on addings are stored in a string comment to a position in the following format: number of addings/last trade price/last trade volume.
The initial position can be opened any time when the current candle’s body exceeds the PriceStep threshold, as well as add to it when the threshold is exceeded at a new bar arrival.
