In line with previous posts, be careful with this simplistic method.

PSar is good as trailing stop componentry to your EA but as Entry/Exit it is more often than not destructively lagging.

As you have already discovered, it will murder your account in sideways market.

I encourage you in your endeavor but I know much about this indicator and it's shortfall. You will NOT find your answer in this one PSar alone. It is too slow.
