Cross_Line_Trader - expert for MetaTrader 5

It is a semiautomatic Expert Advisor. It opens a position at the intersection of the lines drawn on the symbol chart.

Four types of lines are supported

1. Trendline
2. Trendline by Angle
3. Vertical Line
4. Horizontal Line

Three types of interaction with the lines are possible

1. Opening a position in the direction indicated in the line description;
2. Only buying
3. Only selling

Once the price crosses the line and an appropriate position is opened, the line becomes inactive (its type changes). The type of the inactive line is set in the settings to avoid reopening after the price crosses this line.

One type of intersection is implemented: at the opening of a new bar, i.e. if the Open price of the previous bar and the Open price of the current bar are on opposite sides of the crossed line.

Intersection of trendlines

The "Ray to the right" parameter of trendlines is checked:

• If it is enabled, then any intersection of this line at any current bar is counted;
• If the ray is disabled, the intersection is only possible when the right edge of the line is on the current bar or to the right of it. If the price does not cross the line before its right edge becomes to the left of the last bar, then the line becomes inactive.

Intersection of the horizontal line

If the open price of the past bar and the open price of the current bar cross the line, a position corresponding to the settings opens and the line becomes inactive.

Intersection of the vertical line

As soon as the current bar opens behind the bar, on which the line is set, a position corresponding to the settings opens and the line becomes inactive.

The volume of positions opened by the Expert Advisor is configured in the settings. You can also set stop loss and take profit in points. If invalid Stop Loss and Take Profit values are specified, the EA will adjust the values to the minimum StopLevel allowed for the symbol.

The Expert Advisor will adjust the lot in case an incorrect value is specified. If the lot is too large, the EA will adjust it in order to be able to open a position. If there is no money for opening even the minimum lot, no position will be opened.
