Indicator based on other indicator and closing price, not sure how...

[Jean Sebastien Paquet]

Hey everyone, I'm currently writing code for an indicator that uses the price[i] version of OnCalculate instead of open[i],high[i],low[i],close[i] version because that's the simplest way I found, so far, to be able to choose to apply the indicator to another indicator if I want, using the parameters tab in the indicator settings. But I just realized that when I apply it to another indicator's buffer, and can no longer use price[i] to access the array of actual prices, which is something I need to do with this indicator. So I'm screwed in a way because now I think switching to the price[i] version of OnCalculate may have been useless afterall. I'm wondering what you think is the best solution for something like this... I'm a bit new to writing indicators and I want to do it the right way so if any of you have any advice, I would really appreciate it.

When using the "price[]" variante of OnCalculate(), you can access OHLC bar data, via the normal methods described in Access to Timeseries and Indicator Data. You just have to make sure that your indexing method is properly aligned and synchronised.
