A cup of black teaThis strategy doesn't seem to have much to do with volatility.

homilyI can't describe the fluctuation rate, barely a relationship of the amplitude of the fluctuation, except for me 90 cycles ago. The opening method of HH, LL is the operation of the Dongch'an channel DC, and the placement is chosen using a uniform strategy. The implicit volatility, or leave it to the experts to describe.

Peanut butter and jellyI don't have the time right now, I don't have the time to think about it, but I'm not really good at coding, so I can't use series. I'm not going to lie to you.
