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
