While paper testing with QC today I recevied a few of these warnings:

Warning: To meet brokerage precision requirements, order LimitPrice was rounded to 30.17 from 30.1703


The price with 4 decimal points is because that I have been trying to simulate a model where my orders become market making by adding a percentage to the current close price.

I could round the prices in my own code to avoid this warning but was just wondering what the precision requirements are. Is it that it should have two decimal points?
