I'm interested in doing equity pair trading. Does Ninja support being able to chart a stock pair as one entity? For example could I chart 5*KO - 3*PEP? And trade this off the chart. Buying 1 would mean long 5 shares of Coke and short 3 shares of Pepsi instantaneously. If Ninja can't do this what other software allows you define a stock spread and trade it off of a chart? Thanks!
