Could you please add a tool that calculates percentage of either a low or a high? It is currently possible to do it with the Price Extension (PE) tool, but it is very clumsy.
It is a valuable tool to have. Proof of its value can be seen in Chapter IV of Gann’s book 45 Years in Wall Street.
Page 33 and onward is well worth reading.
Cheers, Lester
ps If you do, I would suggest default increments of multiple hundreds of percent. IE 100% 200%… etc.
