This is a grid Expert Advisor which works with market orders using Martingale. The first trade is opened when the price touches a horizontal line placed at a trader's discretion.

The EA has pretty flexible settings — trading lot and step for opening new orders can be fixed or dynamic.

To start using the EA, set horizontal or trend lines and name them according to BUY_Line and SELL_Line parameters.

Default names of these lines are BUY_Line = BUY and SELL_Line = SELL. In other words, when placing a horizontal line or a trend line on the chart, it should be named SELL or BUY.

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

CAUTION. To test the EA in the strategy tester, enable the visual mode, place at least one trend or horizontal line and name it as aforesaid.
