trade_on_close question

[noahberhe]

Hello!
Sorry for the Python OOP question, but hoping someone could give me a pointer?

So I've implemented a simple breakout strategy. To simplify it: say I want to enter a long if High[-1] > High[-2], would the next() function mean I'm entering my trade on the Open AFTER High[-1], ie. not on the Open of the same candle that produced the signal?
Or would it enter the trade on Open[-1], and hence I need to change my signal to High[-2] > High[-3]?

I thought the latter might be true from looking at the code... but then looking at e.g. the crossover function in lib, it compares [-1] and [-2] to create the signal, so I thought perhaps not?

Really appreciate the advice, I've racked my head trying to sift through the code, but I'm still getting to grips with OOP.

Thanks,
Noah

Yes.

No.

Think of it simply as next() executing in-between subsequent bars.

Thank you, and as a follow-up to that, I am sizing each trade based on a maximum 2% Portfolio Equity loss, so I need to access my current portfolio's equity (I'm using self.equity which works), and also the actual traded price, how can I access this?

And to add to that: how can I access trade_on_close, so that I can also use that as a parameter to help calculate my trade size?
