The Expert Advisor opens orders when the price crosses the trend lines. The product can trade both roll backs (Bounce off level) and breakthroughs (Breaks the level).

1. Bounce off level - when the price crosses the support line, a SELL order is opened; when the price crosses the resistance line, a BUY order is opened.
2. Breaks the level - when the price crosses the support line, a BUY order is opened; when the price crosses the resistance line, a SELL order is opened.

To start using the EA, set the trend lines and name them according to Support and Resistance parameters (Sup and Res, accordingly). In other words, when placing a support trend line on the chart, it should be named Sup, while a resistance line should be named Res.

You do not have to use both lines simultaneously. The EA can work with only one of them.

After opening an order, the EA updates its comment to a trend line. If this comment is not deleted, the EA does not open new orders in case the price crosses the line again.
