Fidelity is probably best because they have no api for bot trading the wholesalers will likely give the most price improvement. Robinhood is the most likely to get you worst fills, all the wsb crowd is RH heavy. Schwab ToS sits in the middle, they have better view of the chain and analysis features. But you are missing IBKR Pro. It gives you direct to exchange access and if you have a certain degree of expertise it is the best place to walk the book and work on your fills. Lots of algo support for trying to get you better fills, you can also layer the book with hidden orders to wait it out. Place a visible bid or offer at better than the MM price and then place a hidden order near the mid. Those will get you some pretty decent fills at mid for very wide tickers.

eto pong app sa post niyo, is it IBKR po?

I’ll use it when an IBKR add on appears :)

No problem, and yes I trade manually. There might be an issue with your automated system on getting those fills with less slippage. The exchange has no obligation to fill your order and can refuse them unless they get the price they want. If it’s set up to cancel and only accept orders at a certain price compared to the bid/ask, they might never get filled and rack up a lot of canceled orders because the exchange will not fill the order. It will be very interesting to know though. IBKR has some advanced orders that work the bid/ask for professional traders, so I would assume there has to be some type of success with this automated trading because they get better fills for professional traders. 

"do not open IBKR app drunk" is going straight into the WSB hall of fame

Depende sa time horizon, risk appetite, at setup na gusto mo. Ako personally if kaya ko $100 a month dinedeposit ko na since wala naman deposit fee e. Tas kahit nakatambay lang yun as cash sa IBKR accnt ko ok na yun. Dinedeploy ko yung cash depende sa gusto ko na presyo ng mga inaalagaan ko na ETF/Stock or kapag nagrerebalance ako ng holdings ko. Focus lang sa accummulation.
Mas ok siguro aggressive na monthly mag-invest kapag super bargain. Slow pace accummulation naman kapag nasa ATH, but regardless of market activity try to be invested at all time.
Eventually, kapag low-cost na funds (assuming ETF bibilhin mo) naman binili mo, magiging minimal na lang yan mga brokerage fees & expense ratio especially kapag longer time horizon (e.g. 40yrs to perpetual)

The rule is not a Robinhood specific rule. It’s mandated by the exchanges themselves.
Many brokers DO NOT support traders who become professional traders: https://support.tastytrade.com/support/s/solutions/articles/43000435379
The brokers must likely to support it are those who charge you commissions for each trade and send your orders directly to an exchange like IBKR and Lightspeed.
See some discussion here: https://www.elitetrader.com/et/threads/390-professional-orders-rule-390-rule-some-questions.382741/

You will be labeled professional at any broker for going over 390, all brokers must comply. You don’t want this label at all, your fills will suffer. Use additional brokers and keep average down. If you trade from mobile, Webull is the fastest with one tap entry and exit using turbo trader. If you are using desktop apps, Webull is still fast. Other brokers have desktop apps that are pretty fast but don’t make the mistake of choosing Fidelity. Webull, Schwab, and TradeStation are my favorites, Etrade is pretty decent and IBKR is a little clunky and has disconnect issues but if that’s all you have, you can make it work. If you like using the ladder, Webull, thinkorswim, and TradeStation are the ones you want to choose from. 

Check r/Bogleheads but make sure to only read non-US posts. Or check r/singaporefi or r/eupersonalfinance to see what most of them do with their investment portfolios. Clue: Bogleheads for non-US investors, so Irish-domiciled accumulating ETF/s on the London Stock Exchange via IBKR. Read up on it bec personal finance means you need to learn it yourself.

I’d check with both brokers before moving anything. If it’s a direct in-kind transfer between ISKs, the main thing is whether Avanza charges an outbound transfer fee and whether IBKR accepts that specific security type.
I would avoid selling just to move brokers unless you have to. Selling creates unnecessary friction, especially if you have large unrealized gains. A direct transfer is usually the cleaner route if available.

Wrong sub dude.
\~IBKR has paper trading doh)

TradingView for charting and execution practice, but Interactive Brokers (IBKR) paper trading if you want to experience real-world fill slippage and fees

I let a MCL futures contract expire, tried to cancel it but was too late. Will IBKR auto close the position in the close out period? support said it will settle in cash overnight but just checking here what people's experiences are.

One of the shittiest trade ever.. Wondering if I'll get this shit assigned (it's deep in the money already)? Long call will be worth nothing in a few days once they start unlocking.
Stock might go down even further to 75-80 range next month (today it closed at 119)... By the end of this year below 40.... Moral of the story - do not open IBKR app drunk. Do not mix trading and drinks 🤣

LEI code renewal for IBKR Corporate Account in Italy: cheap & fast platforms? (GLEIF sync time)

I use [Freedom Finance](https://freedom24.com/invite_from/6022216) (FF) in Europe (not a lot of brokers available for me, tbh) and have IBKR account, so can compare only them.
Buying european accumulative ETFs in FF may result in slightly lower fees (tariff "smart") than IBKR. Still depends on order price and number of stocks.
USD FF margin cost is huge (~18%). So if you use margin, IBKR (~4-6%) is indeed much better option.
Withdrawal fees seem better at FF (7 eur) vs IBKR (8 eur / 10 usd) on paper, BUT IBKR allows 2 free withdrawal requests per month, that is again "+" to IBKR.
FF interface is easier / user-friendly, but I don't see a problem with IBKR after using it for several years.
FF has different promotions from time to time that may result in bonus stocks for account top up (still I would not expect to get anything costly there, more like small fun bonus). I don't see such in IBKR, but really think that is negligible
I don't use options, so don't know the fee difference in this area.
So, if retail investor trades a lot with margin and does monthly withdrawal, IBKR seems to be a better option vs Freedom Finance. Long term European market smaller fee difference is negligible, imo, but tiny "+" may be with Freedom Finance. Still there may be better local brokers in Europe that are not available for me.

Depends on what you trade. Fusion markets are top tier for forex, commodities and indices. IBKR are best option for stocks

XTB is super simple a good if one plans to invest small amount regularly. IBKR is a bit more complicated but better option if one plans to invest higher amount regularly. (imho)

I was wondering if the share lending is only effective on some small companies that everyone expects to go down or if you ever get yield on "safe" big companies.
Also who are those shares lent to? Since you can't short normal stock shares within invest or ISA T212 accounts (as far as I am aware), is this lent to CFD traders? Or is this used within some bigger structure with IBKR or other banks?

Can a non-U.S. tax resident living in the U.S. buy UCITS ETFs on IBKR?
