BTC LONGS VS SHORTS (With Demand of USDT)

General idea is like this:

Go long when RULE 1 and RULE 2 are true:

• RULE 1 - when USDT is in high demand (background is green)
  
• RULE 2 - when Longs/Shorts is just recovered from Lower Bollinger Band
  

go short when the opposite is true.

you should also be careful and be prepared for a rise / fall when [Longs/Shorts] is below / above the purple dotted lines


you may want to ignore RULE1 since Bitmex doesn't use USDT to trade

This seems to work for the recent bear market while prices is driven largely by BTC margin or futures trading.
The rationale is that when a lot of people go short, the whales or the exchanges (who are of course unethical) will try to do the opposite to liquidate the accounts of retail traders.
