The Expert Advisor performs the opening of trades by the signals of the Dual-Channel indicator, as well as their maintenance. The root-mean-square moving average is used as an auxiliary indicator. The long trade is opened when the Dual-Channel indicator "draws" a blue arrow, the signal candlestick is located above the moving average, directed upwards. The short trade is opened when the Dual-Channel indicator "draws" a red arrow, the signal candlestick is located below the moving average, directed downwards. Examples of trades are shown in the screenshots.

The trade maintenance settings use the take profit (trade target level), stop loss (maximum loss level), breakeven level - the distance in points after passing which the stop loss is moved to the opening level + spread, profit step - the distance in points after passing which a part of the position is closed, profit factor - percentage of the partial position closure, trailing stop - the level to move the stop loss from the price ((activated after breakeven).

The EA cal also limit the time allowed for opening trades - start and end hours. Maintenance and closure of trades works without limitations
