Undesired price rounding on penny stocks

[Phoenix2518]

I'm trying to monitor penny stocks, which in Thinkorswim are displayed with four significant figures after the decimal point. However, MarketDataEventArgs.Last and MarketDataEventArgs.Price both round to two figures, so for example 0.0288 is rounded to 0.03. This rounding is ruining my algorithms.

I'm connecting to the same account I use on Thinkorswim. Is this data being rounded by NinjaTrader, or by TD Ameritrade? Can I display more significant figures?

That worked very well, thank you. I was even able to multi-select the entire stock list and apply the change to all of them.
