PARABOLIC SAR

I need a robot based on Parabolic SAR with adjustment function for the parameters. And, must contain take profit parameter. Furthermore, the robot must open a position when the dot change side. Ex> When the dot goes down the EA must buy and contrariwase.

SL: when dot change side.

TP: adjustable.

*The robot must close all open positions to open a new one / Never keep contrary side positions.

> Do not use martingale for this system.
