Multi Instrument Comparison
This instrument is useful for charting a portfolio (or combination) of stocks and ETFs and comparing the resulting equally weighted performance to another set of ETFs.
The lower part of the instrument displays the performance difference between the two sets of securities. It is useful in determining the trend of performance, as well as the correlation of returns between the two portfolios.
Signal Sigma Pro features a similar instrument where you can plot the performance of any sets of instruments (not just ETFs on the Comparison Ticker selection)
