Infinite grid strategy

[arthurwolf]

This is a feature request for the "Infinite grid" strategy, a variant of the grid strategy that does not stop trading as the price goes over the maximum value in the price range, and just keeps creating more grid points as prices goes up.

It is for example documented here: 

• https://support.bibox.jp/hc/en-us/articles/900001354963-What-is-Infinite-Grid-Trading-
• https://help.bituniverse.org/trading-tutorial/trading-bot-tutorial/infinity-grid-trading-bot
• https://www.pionex.com/blog/pionex-infinity-grid-bot/

This could maybe be implemented as an (extra/optional) option to the existing grid strategy? Or as a separate strategy maybe if not.

I'm ready to pay for this to get implemented if somebody is interested in that.

Edit: OH LOOK somebody already did it : https://github.com/jnlin/bbgo-strategy-infinite-grid !!!
