RE: L2 Ondariis VS Fairchij not the same...@ Montreal. I believe the difference between is that Fairchi reports the number of "lots" for bid or ask. In contrast, Ondariis reports the number of shares in thousands. For stocks between 10 cents and $1, the lot size is 500. Therefore, if you double the number for bid or ask from the Fairchi report, it should equal the shares on the Ondariis report.
