Why stock prices in the pre-market different from other platforms

1. Data sources: The pre-market prices of free users based on Nasdaq Basic LV1 data. Users can get complete extended market data by paying to upgrade to National LV1 data.

2. Odd lots: Round lots are defined by the exchanges and generally refer to quotes to buy or sell 100 shares of a given security or a larger number of shares divisible by 100. Odd lots, or orders for fewer than 100 shares, are not included in the NBBO and are not currently distributed by the SIPs.
