The EA trades on indicator Moving Average, all the preparatory and trading functions having been implemented as the CMoving trading class in a separate file named Moving.mqh.
Inputs
magic number – the unique EA identifier;
Lots – position volume (the position volume above zero or risk size above zero may be specified);
Risk – risk in percents of free margin per trade (the position volume above zero or the risk size above zero may be specified);
MA: period – indicator Moving Average: Timeframe;
MA: averaging period – indicator Moving Average: Averaging period;
MA: smoothing type – indicator Moving Average: Averaging method;
MA: type of price – indicator Moving Average: Type of prices, on which the indicator is calculated;
Take Profit – Take Profit (for the case where one position is open);
Lot multiplier for a series of Positions – increasing the volume of a position for a series of positions;
Distance from Moving Average – distance from the Moving Average indicator;
Additive in the presence of the general profit – adding to the indent, if there is general profit.
The EA uses the swing principle, there being a possibility to increase the number of lots; a simple strategy is used for its operation:
If the price is above the Moving Average indicator at a pre-set Distance from Moving Average, we will open a BUY position;
If the price moves down from the Moving Average indicator at a pre-set Distance from Moving Average, we will open a SELL position with the same lot;
If the price has moved up from the BUY position having the highest price at a pre-set Distance from Moving Average, we will open the next BUY position;
If the price has moved down from the BUY position having the lowest price at a pre-set Distance from Moving Average, we will open the next SELL position;
