Correlation Based Pair Trading Strategy (Trading the spread)
There are three popular styles of Pair trading:
* Distance based pair trading
* Correlation based pair trading
* Cointegration based pair trading
The correlation based strategy is to short the outperforming instrument and go long on the underperforming one
whenever the temporary correlation weakens which means one instrument going up and another going down.
Here, instead of two different instruments two timeframes of the same instrument are used, lower and higher.
In order to calculate the trade size, we would need to calculate hedge_ratio,
which is simply the ratio of the closing price of the instrument in the current tf to the higher tf.
So whenever we want to go short on spread we’ll short 1 unit of current tf and go long on hedge ratio times units of higher tf.
In order to generate trading signals, we need to define our trading logic.
So, we’ll go long on the spread when the hedge ratio goes below its p rolling mean by mult times of its
rolling standard deviation and vice versa.
Note that both p and mult can be changed as per your selection of instruments.

NOTE:
There is a minor problem to it in Pinescript. After a while the signal line goes horizontal and the two bounds, upper and lower, converge unless you update the time frame.
