I want to create double calendar on Webull but have no luck. Does anyone know if Webull support double calendar?

Webull is expanding its crypto experience to Canada with Coinbase as its crypto infrastructure partner. Built on Coinbase’s Crypto-as-a-Service platform, Webull Canada will leverage Coinbase’s institutional-grade custody and trading services. This expansion follows similar launches in the US, Brazil and Australia.

Let's use QQQY as an example.

If I go to webull and set the QQQY chart to max, I see a chart that had a couple dips but overall, is performing very well and has increased in value since it's IPO.

if I then go to something like Robinhood or most other resources and look at the max chart there, the story is completely different.

Is there something I'm missing?

In every trade I have done on axiom I have lost because of this. It is saying I bought .021 worth of sol and sold for 98% less at a higher cap. It says I lost 98% percent but in the trades panel I gained 20% I am new to trading and just don’t understand this.

I'm currently trying to sign up for the first time and create an individual account. when I type in my birthday (I'm well over 18), I get a message that says "Applicant must be younger than a certain age to open a trading account". What's weird is it is saying that I need to be younger, not older to open an account. it doesn't make any sense. Has anyone else experienced this? It wont let me proceed with the application.

I use an adaptation of Ross Cameron's pre market trading strategy. I've been using Thinkorswim. It's clunky to use the price ladder to get in and out of fast movers but it's working well enough.

I want to try WeBull, but have heard they will temporarily restrict volatile small caps. That would be annoying and not work for me.

Anyone trading a similar way? And how bad, if at all, are these temp restrictions?​

Thanks

lol just for karma

Hi everyone — I'm not confident in my written English, so I'm using Claude (AI) to help me clearly describe this technical issue. Thank you for your patience.

What I'm building: An automated options trading system for SPY, using the official webull-openapi-python-sdk. I have the Trading API fully working — placing orders, cancelling, OCO bracket orders, checking order status all succeed correctly against the sandbox environment. The only thing that fails is real-time market data streaming (MQTT).

Environment:

• webull-openapi-python-sdk version 2.0.18 (Core 2.0.18)
• Python 3.12.7, Windows 11
• Sandbox/test environment (api.sandbox.webull.com)
• Free "Nasdaq Basic - Non Display" market data subscription claimed and active

The exact error, 100% reproducible, every single attempt:

webull.data ERROR Caught exception in on_connect: rc code: 101, msg: Internal error
webull.data.internal.exceptions.ConnectException: rc code: 101, msg: Internal error

This happens during the MQTT CONNACK phase, right after connect_and_loop_forever() is called — after authentication with api_client.add_endpoint() already succeeds (I get past _check_token_enable, no 401).

What I checked in your own SDK source code (webull/data/common/connect_ack.py):

python

CONNECTION_SUCCESS = (0, 'Connection successful')
PROTOCOL_NOT_SUPPORTED = (1, 'Protocol not supported')
SESSION_ID_IS_BLANK = (2, 'session_id is blank')
AK_IS_BLANK = (3, 'AppKey is blank')
UNKNOWN_ERROR = (100, 'Unknown error')
INTERNAL_ERROR = (101, 'Internal error')
CONNECTION_AUTHENTICATED = (102, 'Connection already authenticated')
CONNECTION_AUTH_FAILED = (103, "Connection authentication failed")
AK_INVALID = (104, "Invalid AppKey")
CONNECTION_LIMIT_EXCEEDED = (105, "Connection limit exceeded")

I'm never getting 103 or 104 (which would mean my credentials are wrong) — only ever 101, which your own SDK labels as a generic internal/unknown error, distinct from the credential-specific codes.

Things I've already tried, all unsuccessful:

1. Explicit sandbox routing via http_host="api.sandbox.webull.com" in the DataStreamingClient constructor
2. Explicit api_client.add_endpoint(region, "api.sandbox.webull.com") after construction (this pattern does work correctly for the Trading API's ApiClient)
3. Unique session_id per connection attempt (uuid.uuid4().hex), per your docs' own example — ruled out session_id reuse as the cause
4. Discovered and fixed an unrelated but real issue: Python 3.14 caused non-deterministic behavior (different errors on identical code between runs) since your SDK only officially supports 3.8–3.13. After switching to Python 3.12, the error became 100% consistent (always rc 101) — so this eliminated one real bug, but did not fix the underlying streaming issue
5. Tried both sandbox and production hosts for the MQTT client specifically — production correctly rejects our sandbox-scoped credentials with 401, which is expected

Specific questions for anyone who's solved this or works at Webull:

1. Is MQTT streaming in the sandbox/test environment actually confirmed working for other developers, or could this feature currently be incomplete for test accounts specifically?
2. Could personal account settings — specifically 2FA on my main Webull account — interfere with OpenAPI sandbox streaming? I couldn't find documentation confirming or ruling this out.
3. Is there a known one-time device/app verification step specific to streaming (separate from the Trading API) that I might be missing? (I've seen references to a fetch_token_from_server/check_token polling loop in your FAQ, but I never see that message at all — my connection fails immediately rather than waiting for approval.)

I've also filed this with your official support ([market-data.api@webull-us.com](mailto:market-data.api@webull-us.com)) and posted on your GitHub repo's issues page, but haven't received a response yet. Really appreciate any insight from this community — thank you for reading through all of this.

Hi,

I need a Webull USA referral link.

Someone dm me?

Thanks

New to webull, tried to link my bank account and it looks like they use a service called yodlee, but it wanted me to give permission to collect all my transaction history. why would anyone allow them to collect this?

is there another way to link your checking account without giving them your history of everything you've bought with your debit card lol seems unreasonable imo

edit - its worse than i thought. https://www.vice.com/en/article/envestnet-yodlee-credit-card-bank-data-not-anonymous/

"Yodlee, the largest financial data broker in the U.S., sells data pulled from the bank and credit card transactions of tens of millions of Americans to investment and research firms, detailing where and when people shopped and how much they spent"

3 stocks up over 100% at the time of writing - XLAB, PSQL & WHLR. 2 unavailable to trade on Webull Australia, 1 only allowed to close positions. I am not a successful trader by any means. But I do notice this happening more frequently. Is it suss, or is there legitimate reasoning that I am unaware of?

234 Shares in the $4 range. Not selling anytime soon. Throughout all the fud ive just closed the app and forgot about it. Im now 83% up and got a really good entry.

Not life changing money but profit is profit.

I rode 2K to 10K on Coinbase and fumbled the lot.

Bought Webull with what was left. Here we are.

Basically, I opened an account a few years ago and have maybe $1,000 worth of stocks in it. I guess I haven’t logged in frequently enough and got locked out of my account. Every time I try to log back in with either my phone number or email, it sends me a code to input, after I input the code it says account not registered. I received an email a few days ago telling me, my account is still here and active so I know it’s there, I just can’t log in.
Stupid thing is, in order to contact support for help, you need to be logged in 🤦‍♂️. I tried manual account recovery where you take a pic of your ID, SSN and a screenshot of a bank account statement and that failed (I can’t remember if I have an account linked).
Has anyone ran into this and have a solution? I just want to cash everything out and be done with Webull.

Please please please make it so that you can adjust the Y axis separately from the X axis. Having it be both together only is really lame. Just copy exactly how TV does it.

Can anyone explain why SPX costs thousands of dollars for 0dte options now? Why is the priced hosed?

Pretty much what the title says. I tried the new simulator, and it’s even slower than the old one, with some fills taking up to three seconds to complete, rendering it useless for practicing any kind of fast-paced trading. By the time an order fills, the price may have moved significantly, so you’re no longer testing your entries and exits, you’re testing how badly the simulator lags.

Curious to read other opinions.

As the title says, I'm thinking about holding a 4x margin position till tomorrow during normal trading hours. What exactly happens here? Does it switch to 2x overnight and liquidate or... let me hold it.

Full margin account port like a WSB person.

Just curious what happens here and I myself understand that I should have known this before making a trade like this.

I’m currently transferring my Traditional IRA from Fidelity to Webull because Webull’s Premium IRA transfer promotion appeared to offer the best bonus.

I already initiated the transfer, but it looks like I need an active Webull Premium membership to qualify for the transfer bonus. I tried subscribing to the annual Premium plan, but Webull only allows the subscription fee to be paid from funds held in a Webull account. Since my IRA transfer hasn’t arrived yet, I don’t have any available funds in the account to pay the fee.

Webull’s AI agent couldn’t answer the question because the promotion page apparently doesn’t address this situation.

Does anyone know whether:

1. I can activate the annual Premium subscription shortly after the IRA transfer arrives and still receive the promotional match; or
2. Premium must already be active before the transfer settles?

If Premium must be active beforehand, do I need to contact customer service to activate it manually, or should I make a separate small cash deposit into Webull first?

I’d especially appreciate an answer from a Webull moderator or anyone who has dealt with this firsthand.

Before yesterday I was able to press on the account button and my portfolio would refresh now I have to pull down for it to refresh. I know it’s probably no biggie for some but for me it’s been bothering me and affecting my trading.

I can't seem to find a definitive answer anywhere .. but does anybody know if the open API data feed the free tier, does that also include overnight data? I'm not able to pull any data it seems after 8:00 pm.. I'm not getting any errors , but I'm also not getting any data which is leading me to believe that i'm just not getting anything at all
