* Add clarifications of instructions and limitations:
This indicator can approximate the amount of liquidations (ie, bars where there were a lot more liquidations than others) from the difference between futures and spot, but it cannot distinguish the proportion of shorts versus longs liquidations, it is instead approximated with the current price bar's color, which naturally suggests where the majority of liquidations happened (ie, if a price bar closes above open and hence in green, then we can suppose that a majority of liquiditations were on shorts, since we know longs won). This explains why there is only one liquidation bar but colored, and not two, since we cannot separate longs or shorts liquidations.
