Code to add preceding candle as a condition

[snoinvest]

I'm trying to create a pullback/breakout indicator. I have correctly defined a PullbackCandle with a bool function. I want to now define the BreakoutCandle as the candle that makes a new high vs the previous candle only if that previous candle is also a PullbackCandle (that's critical). When I try to use a bool function with something like this: bool isBreakoutCandle = isPullback[1] && High[0] > High[1], I get a "cannot apply indexing with [] to an expression of type bool. What would be a work around that?

Thanks in advance.

Hello snoinvest,

Thank you for your post.

Is isPullback a bool? This would likely be why you are getting the error if this is the case, bools can only contain true or false values. Indexing [] can only be applied to things like series.

You could instead define it as a custom Series<bool> which would hold a collection of true/false values. Then you could store a true or false value for every bar, and access it via indexing i.e. isPullback[0] for the current bar processing, isPullback[1] for the previous bar, etc.
