Hi everyone,

I'm new to IBKR and just made my first big ETF purchase, and I think I paid too much. I'd like to understand what went wrong and how to do it better next time.

What I did:

- Manually converted CZK to EUR on IBKR first, so I had about €20,435 in EUR cash.

- Bought WEBN via the IBKR Android app.

- Used a Market order, time in force Day, whole shares, with a small cash buffer for commission.

- I placed the order at around 14:30 CET on 05.10.2026.

What happened:

- The price shown when I submitted was about €12.94 per share.

- My average fill price came out at €13.30 per share, about 2.8% higher.

My questions:

1. Is a gap this big normal for a market order on this ETF, or did I make a mistake?

2. What order type would you use to buy about €20k of an ETF at the best possible price without waiting days for a target price?

3. What do you check before placing the order?

4. Is there a best time of day to buy European ETFs, or times to avoid (open, close, lunch)?

5. Would splitting the purchase into several smaller orders help, or does it just add commissions?

6. Should I choose a different exchange listing in IBKR to get a tighter spread?

7. Is there a way to see the fill details in the app, so I can tell whether the price moved before my order or I got filled in pieces at rising prices?

Any advice or past experience with a similar situation would help a lot. Thanks!

A relative lives in the US but has a Canadian bank account. They want to transfer CAN$ to IBKR, and trade the CAN$ to US$. This is to avoid the 2% markup fee that Canadian banks charge for any Canada-to-US transfer.

The problem is that this requires a wire from the Canadian bank to the Canadian brank of IBKR. But the Canadian banks won't let you do a wire between Canadian banks unless you are present. My relative doesn't want to travel up to Canada just for this reason alone.

Has anyone done this before and have a better process to follow? Note both of us have contacted IBKR and their support has been no help.

Hello, I would like some help with a question regarding an IBKR account with $55,000 invested in T-bills: what is the maximum amount of margin I can borrow against that capital?

Just want to know if anyone actually used the API for real money. Have you had success with it? Are there any drawbacks to it?

Hello...I'm planning to move from the UK to Thailand in a couple of years. I have looked through the help files and I understand the requirements for changing residency. I also understand that my account is going to be migrated from the UK to the closest one to Thailand (not sure if AU or USA). What is not clear to me is if I will lose the ability to invest in European ETFs, UK Gilts, or mutual funds from the UK. Is there a way to check which products are available once I move to Thailand?

Is it possible to convert currency from USD to CHF on existing holdings to get a better margin rate? I need to pull some funds from the account and do not want to trigger capitol gains but would be OK on the risk on the currency especially when the rate is 3.5% less.

Wanted to write this up properly since it's a real platform behavior that can bite you even if you're not doing anything unusual — just holding a position with a normal resting stop order.

Here's what actually happens: during an extended-hours price move, IBKR's own price collar mechanism can reject a routine update to a resting stop order and, as a side effect, cancel the entire order server-side. No error message anywhere. No notification to the account, no alert in TWS that I could find after the fact. If you're not actively watching your open orders screen at that exact moment, you'd have no way of knowing — the position just sits there with real shares and zero downside protection until you happen to check.

I only caught it because I'm running an automated system that checks positions against their expected stops on a schedule — traced it back to the collar specifically by going through IBKR's own order history after noticing the stop had gone missing, since nothing in the live data pointed at the cause directly.

Went looking afterward for whether this was a known issue and found several older threads (some multi-year-old at this point) of other people independently describing the exact same thing — a stop that was there, then wasn't, with no warning. So this isn't a one-off glitch, it's a real recurring gap in how this particular rejection gets surfaced to the account holder, or rather, doesn't.

If you place stops manually and check your account reasonably often, the practical mitigation is simple: after any extended-hours volatility on something you're holding, it's worth double-checking your open orders rather than assuming a stop you placed is still there. If you're running anything unattended — even a simple script, not just a full trading bot — the real risk is higher, since nothing will tell you it happened; you'd only find out when the position's already fully exposed.

Has anyone been able to start trading single name futures with IBKR? They don't even show up when searching for them. Tried Nvidia, Intel, and many others with no luck. Anyone else?

If i have cash in USD or MXN does it gain any interest?

If i wasnt sure where i wanted to invest right now, which is the safest options for me?

For USD i guess it would be USFR or SGOV, how about for MXN?

Has anyone figured out a way to manage option orders and have multiple exit targets? I day trade options and looking for an efficient way to scale out. Currently manually scaling out from positions. Are there any order management APIs out there or ways to pre program my exit trades on options? Thanks for any feedback.
