This adviser finds the trend of the currency pair on a given number of bars, after that, determines the time of the correction. If the trend is strong enough, and the correction becomes equal to the one set in the parameters, the adviser can open a trade in the direction of the trend, if additional indications of indicators confirm the opening of the trade. This is good because it will not buy at the high or sell at the low of the trend, but only after the correction. Nevertheless, it is possible to set different values ​​of correction, and even 0, if you need to trade only when a trend is found.
