Noob...how do I obtain previous day high, low and close??

complete noob here....

I coded an indicator in strategydesk as follows (inner bar strength)
(Bar[Close,D,1]-Bar[Low,D,1])/(Bar[High,D,1]-Bar[Low,D,1])

Can one point me to the documentation that shows how I grab historical data for manipulation?
I'm not looking for someone to code this for me (though that would be great). I am just trying to learn.

Ideally want to add this as an indicator.

Thanks!

Hi,

In QS language, you can reference a previous bar using the "ref" function or using []

Example:
a = ref(close, 1);
OR
a = close[1];

Your example:
a = (close[1] - low[1]) / (high[1] - low[1]);

This assumes Bar[Close,D,1] is searching for the close price one bar ago.

If you are looking for current bar data then use:
a = (close - low) / (high - low);
