haven't seen this published, so i made it to watch my position while looking at my TV chart
right now, code works for just linear contracts (base currency margined, not quote currency) and i will have to add the code for inverse perps soon in the next update
very simple tool... not much to explain
just enter
long or short
average entry
position size (designed for btc since i'm a maxi, but entering the amount of any base currency should work)
take profit
then you'll get candles for your position and a line for your TP (and its amount)
next version will add a feature to plot inverse perps
(sorry TV if this doesn't abide by the House Rules exactly)
