How to properly calculate "tick charts"

Discussion in 'Trading Software' started by Shmulik2828, Dec 20, 2006.

  1. When calculating a "tick chart" does one just select a number, e.g., 89, and aggregate 89 trades to define a bar, or is there some sort of calculation including volume?

    That is, if I get three trades from my data feed going through (assume ES contract) as follows:

    Trade# Price Volume(contracts)
    1 1420.25 10
    2 1420.25 1
    3 1425.50 3

    Would this is considered "3" ticks or "14" ticks? Or do people use some other calculation?

    I believe this would be counted as 2 ticks for tick charts and 14 contracts for volume charts.
