background:

there are ways to represent the position accumulation for the crypto or stocks.

The higher the position accumulation or lower volatility, the more people hold positions with similar entry prices. Since that, once the price has big volatility, every holding trader needs to react to the volatility.

the following graph is for volatility from adding up absolute difference value from the moving averages or adding up Standard deviations from multi-windows.

it is welcome for the following works

1. a better way to evaluate position accumulation or volatility
2. design breakthrough or market-making strategy based on different volatility
3. a predicted method to select the crypto or stocks that will have increased volatility, maybe related to some rank or pannel data method.
