The Expert Advisor draws 4 lines: "BUY LINE", "SELL LINE" и and two corresponding "CLOSE" lines.
Your task is to move the lines to the prices you want to operate - to Buy, to Sell, or to Close.
The orders are set and close at the moment then price crossing the line, for example for Buy case: if the Ask price crosses "Buy LINE", and for Sell case if the Bid price crosses "SELL LINE", the same is for "CLOSE" lines.
Here is a trade example at figure
The total number of lines can be reduced using the lines
DRAW_SELL - draw Sell line
DRAW_BUY - draw Buy line
DRAW_CLOSE1 - draw Close1 line
DRAW_CLOSE2 - draw Close2 line
There are some external variables: lot - lot size and order - maximal orders allowed. The CLOSE lines can be used for a trailing stop, just choose right angle.
