Description
In /contrib/strategy/signal_strategy.py,
it comments
"get the number of trading step finished, trade_step can be [0, 1, 2, ..., trade_len - 1]"
If set finished == self.trade_step >= self.trade_len it will raise IndexError: index X is out of bounds for axis 0 with size X.
I think change self.trade_len = _end_index - _start_index + 1 to self.trade_len = _end_index - _start_index maybe better, but it may result in other errors.
