If it helps here is a bit more context. The goal here is to keep the signal bullishg_rolling signal high after we get the first bullish_now signal and until bullish_stop is triggered.

self.bullish = bt.And(super_fast > fast, fast > slow, self.data_low > super_fast)
self.bullish_now = bt.And(1 - self.bullish(-1), self.bullish)
self.bullish_stop = super_fast <= fast

super_fast,fast,slow are EMAs

Hello everyone,

I was wondering if it was possible to conditionally carry values over for a LinesOperation over in init.

For example something like this?

self.bullish_rolling = bt.If(self.bullish_stop, False, bt.If(self.bullish, True, self.bullish_rolling(-1)))

Nevermind :)

self.bullish_now = bt.And(1 - self.bullish(-1), self.bullish)

Hello everyone,

Might be a fairly novice question. How do I detect when a signal toggles from 0 to 1.

        super_fast = bt.ind.ExponentialMovingAverage(period=self.params.superFastLength)
        fast = bt.ind.ExponentialMovingAverage(period=self.params.fastLength)
        slow = bt.ind.ExponentialMovingAverage(period=self.params.slowLength)

        self.bullish = bt.ind.And(super_fast > fast, fast > slow, self.data_low > super_fast)

I tried this but it throws an exception: "TypeError: bool should return bool, returned LineOwnOperation"

self.bullish_now = bt.And(not self.bullish(-1), self.bullish)
