In an attempt to see PnL in terms of pips when dealing with forex, I stumbled upon this thread: #8. In this thread @kernc suggested: pnl_in_pips = self.position.pl / self.position.size / self.data.pip in order to calculate PnL in terms of pips and I inserted into a strategy along the lines of:

class BaseStrategy(Strategy)
 total_pips_gained = 0
 # ...... 
 def next(self):
 super().next()
 exit_portion = self.__exit_signal[-1]
 print("Total pips gained: " ,self.total_pips_gained)
 if exit_portion > 0:
 for trade in self.trades:
 if trade.is_long:
 pnl_in_pips = self.position.pl / self.position.size / self.data.pip
 self.total_pips_gained += pnl_in_pips
 trade.close(exit_portion)
 elif exit_portion < 0:
 for trade in self.trades:
 if trade.is_short:
 pnl_in_pips = self.position.pl / self.position.size / self.data.pip
 self.total_pips_gained += pnl_in_pips
 trade.close(-exit_portion)

With the idea that we'd want to calculate PnL of pips when we close our position.

However, stats = bt.run() outputs Return [%]: 1.6968, while the last print statement for total_pips_gained prints out -1033.8971649107916. Am calculating pnl_in_pips correctly? How is it that return % overall is positive, but total_pips_gained is very negative.

UPDATE:

For shorts: it should be: self.total_pips_gained += (pnl_in_pips * -1)? Since it is the opposite direction! Is this logic correct?

Follow up question: I was not able to find self.data.pip anywhere in the codebase on how it is determined. My forex data is in OHCLV format.

Thank you!
