Trendlines to buy or sell

 I want to drAW from one to six trend lines which can be named:

 b1 , b2 , b3

 s1 , s2, s3

FIRST three LINES OPENS LONG, SECOND Three OPENS SHORTS

don't mind if price is above or below the trendline .

We have also max slippage, max spread, take profit, and stop loss, size, once the line is fitted it is disabled ( a line gives only one trade).

we have also instant trailing stop in pips enabled/disabled. Trailing stop enabled disable tp and sl All parameters are the same for the different lines

I want to be owner of the code, due to bad experience (programmer don't do requested emprovements and 

correction of bugs so I spend money for nothing cause I need to start from the beginnig, worst bug is a rare failure in the setting of the stop which sometimes is not send to broker) 

Kind regards
