⋅ This script lets you chart a spread of a maximum of 3 tickers (one of them being the ticker in the main chart).
Y axis is the currency amount of the spread, that is calculated by this formula:
Y = PnL = quantity * price * handleValue
Y is calculated for each ticker specified, and the sum of Ys obtained is plotted.
this way it is possible to view the PnL of the spread directly.
It is necessary to specify the handle value (point value) in the script inputs (not for the main chart ticker).
A table summarizes the spread configuration, containing all inputs.
