two_leg_spread_returns_zscore

This script helps assess the relative returns of each leg in a two-legged spread. It shows the z-score of each period's returns, along with a moving average of the difference between the two returns. A negative moving average implies that the second leg is strengthening, on a relative return basis, against the first leg, and vice versa. The inputs are:

- timeframe: the timeframe for the calculations. the default is five minutes.
- leg1_sym: the symbol for the first leg
- leg2_sym: the symbol for the second leg
- ma_length: the length of the moving average. by default it is 48, or the previous four hours, given the default timeframe.

The default symbols are RB and HO, simply as an example of an intercommodity spread.
