This indicator was made to streamline finding the optimal entry to cash and carry/hedge on a futures contract when margin trading.

Example of use: On 4 May 2018, BitMEX's XBTU18 was trading >2% above perpetual swap. The grid alerts signaled that and if one were long on bitcoin spot on any exchange, then it would have been a good idea to hedge a short on XBTU18. Eventually from there the premium gap was closed while bitcoin fell.
Here is the indicator shown with bar coloring and labels.
