Calculatring from previous data

[timmbbo]

Hi there, what's the best way to get previous bars for current calculations?

Say I have a strategy that uses the day's average, of each of the last 30 trading days. I know I can do this by backtesting, calculating the value, and then incorporating that value into my current strategy. However, I want to accomplish this without going into backtesting. That would mean my strategy would somehow need access to the last 30 trading days, and calculate the day's average of each of those days.

How to accomplish? Thanks,

Hello timmbbo,

You can call the previous bar with a barsAgo index of 1.

For example:

if (CurrentBar > 1)
Print(Time[1] + " | Close[1]: " + Close[1]);

The PriorDayOHLC() indicator demonstrates getting values from a previous session.
