Since they introduced BTCUSD back in 2018, these have been the funding returns:

• August 18, 2021 - August 18, 2020 = 35.163977%.
• August 18, 2020 - August 18, 2019 = 11.327471%.
• August 18, 2019 - November 14, 2018 = 7.463414%.

That is an average annual return of 18.74%.

Sure! I'll explain what it is and then how it fits into my overall system.

True Range is calculated by looking at the daily price change and using the greater of three calculations:
    (high minus previous close)
    (previous close minus low)
    (high minus low)
The days slider in the calculator is how many days of the above True Range to use to get the Average True Range (ATR). The default is 21 but I personally use 100. The multiplier is just making the ATR result bigger before placing it below the current price at our stop position. The default is 3 but i personally use 8. Using the tool, the current price of BTC is US$9,776.76 and I would place my stop at US$5,659.30 with my personal settings.

The strategy I implement is trend following using end-of-day data with a long term investment horizon (not day trading). I want to buy coins that are trending upwards and ideally hold them forever if they keep going up. If the coin reverses and starts moving down I want to sell it. I use volatility stops to decide one of two things:
    1. The coin has started trending downwards and it’s time to exit the position.
    2. The coin is experiencing it’s normal volatility and is still trending upwards.
I don’t use a set percentage like 15% or a fixed amount like $1000 for my stops. Different coins have different levels of volatility so I wouldn’t be able to decide if the coin is trending up with it’s normal volatility or if the trends reversed.

Works for most cryptocurrencies. For those who want to use a volatility based stop-loss in their exit strategies.
