Trading Robot based on Parabolic SAR

I need a robot which will trade with the parabolic indicator sar. That said I have to change the configuration of the indicator in order to put it to my advantage.

When the sar is above, we sell. The robot will have to place an order for each candle that will open. For this technique there is no stop loss. However, we will put small leverage which will be adjustable.

we continue to sell, it will sometimes have many  open positions at the same time (this is why we put small leverage) . for take profit, the trade will cash gains only on a candle close in profit. If there is not possible for a few hours then we wait. It is really important that all positions only close when they have a close of candle in profit. And thereafter the robot continues to put other position in the direction of the sar.

it will have trend change. So even if we have (X) negative positions, the robot will have to close all the positions (even if they are in loss) And then the robot will have to continue to place orders on the market in the direction of the parabolic sar.

in the configuration of the robot I would like:

-choose the temp measurement ex: m15, m30 h1, h2, h4, D.

-be able to adjust the lever ex.: 0.50 or1.19 or 5.

-I would like to be able to put the robot on various currencies at the same time

-when it will have a change of trend, the robot will have to close all open positions and continue to put positions in the other direction
