Stock-indicators

New indicator:

- True Range (TR) - see 845 for explanation

True Range was always part of the results for Average True Range (ATR), but we're pulling it out independently for people who want to apply any of our available moving average types instead.

- barisertekin and Erdogan34 for the recommendation
