Persistency of trend This script calculates how many days price has been over a Moving Average.
How to use the indicator You can use it to find persistency of trend.
Over a certain threshold - number of days - you will find a very strong persistency of trend that has a high probability of continuing longer than you may first expect. It's up to you to find the threshold numbers. Let's be clear though it's a pretty high number.
You can change amount of days to fewer to find shorter term persistency as well.
Settings You can configure settings of MA and amount of days to fit your needs.
