Connecting Webull without handling API keys

Webull is a stocks connection that you set up by signing in at Webull. There is nothing to generate or paste. This page covers where quotes come from and how fractional orders behave.

Quotes come from Polygon

Webull does not provide market data through its API.

    • Not provided through its API

Fractional shares have a narrow lane

Webull supports fractional quantities to two decimal places, rounded down. Turn on the fractional quantity option in the strategy subscription to use them.

A fractional Webull order must meet every rule

3 of 4 met

  • Met: Time in force is Day

    DAY

  • Met: Order type is market

    Market

  • Met: Long only, no short sale

    Buy

  • Not met: No take profit or stop loss attached

    Stop loss 5%

    Fix: Remove the exit, or send it as a separate signal.

This order will not go through as fractional.

Webull: 2 things that work differently

  • Account No paper trading

    Webull has no paper mode on TradersPost. Rehearse a strategy on the TradersPost paper broker first, or start with small live sizes.

  • Orders Day and GTC are the only times in force

    Webull accepts Day and GTC orders only.

Webull automation questions

How do I connect TradingView to Webull?
Connect Webull with OAuth, subscribe it to a stocks strategy, and point the TradingView alert at that strategy webhook. You do not generate Webull API credentials in TradersPost.
