Access the first candle of the session. next() always give the 2nd element

[Shishir-Bondre]

Expected Behavior

• How can I access the first candle of the session ? I want to test the strategy which takes the trade on first candle.

Actual Behavior

           class Scalping(Strategy):
                     def init(self):
                           pass

                     def next(self):
                           if len(self.data) == 1:
                                self..buy()

Steps to Reproduce

1. Currently I cannot access the 1st price points

           class Scalping(Strategy):
                     def init(self):
                           pass

                     def next(self):
                           if len(self.data) == 1:
                                self..buy()
                                # not executed currently

[bhargavyagnik]

self..buy() is not a correct python syntax, try self.buy()

Si lo que queres es ejecutar en la primera llamada de next podes hacer esto

from backtesting import Strategy

class Scalping(Strategy):
      _order_Scalping = None
      def init(self):
            pass

      def next(self):
            if self._order_Scalping is None:
                  self._order_Scalping = self.buy()

recorda que segun los indicadores que allas configurado, el primer llamado a next puede ser en la fila posterior a los datos que allas proporcionado. Pero el codigo alli te sirve :D
