Added the ability to completely turn off buys during a downtrend. If using this you will want to make sure market trender is tuned well (e.g. by increasing smoothing length and lookback length).
This will allow us to buy buy buy during uptrends, but trigger stop loss (to be added) during downtrends and exit the market. When market looks good again, we re-enter. Especially helpful for BTC markets, I would use DCA for USDT-BTC.
