Is the price/quote of the pre-IPO market different from what you see at other brokerages

The pre-IPO market trading is not through the exchange system, but through the internal system provided by third-party to fix up quotes. EleBank's pre-IPO market is an independent internal trading system, and it is very normal to have price differences with other platforms.

Note: Some brokerages may have access the same upstream, so you will see the same quotes
