Specifies the smallest possible price change for a futures contract.
Tick sizes are obtained automatically when importing data from Norgate.
For CSV futures data import, it would be necessary to provide tick sizes for each contract using a SymInfo file.
If not provided, TickSize defaults to 0.01 for stocks.
Note that TickSize is not used in indicator or other data-value calculations — formulas always see the full precision of the imported bar data. It is, however, the default value of PriceRound, so by default trade prices are rounded to the as-traded TickSize before profits and losses are computed.
