Finding decimal places

sbgtrading · 11-25-2007, 06:49 PM

How can you find the number of decimal places for an instrument with NinjaScript? (e.g. YI is 3 digits after the ".", YM has 0 digits, ES has 2 digits)

I have written a routine to find it, but it's cumbersome. Is there a way to get the value directly?

Please check out TickSize.

Yes...but TickSize does not explicitly tell me how many digits in the valuation.

TickSize for the YI is 0.001, to get the valuation for significant digits (3 in this case), you have to write a routine. One example would be to convert TickSize to a string ("0.001" in this case), and then counts how many characters are after the "." ...not a very pretty solution.

Counting places on a substring is the way I would do it.
