IBKR USA Setup for EU Stocks: Feedback on Fees, Execution, and Currency

General
1

I am in the process of testing EU stocks with Interactive Brokers (IBKR) to run alongside my primary manual trading account at Fidelity. I am still learning the nuances of the IBKR platform and wanted to share my current configuration for feedback.

1. Commission Structure

Coming from a traditional broker, the IBKR Pro "Fixed" pricing minimums ($1.00 US / £5.00 UK) felt high for the frequent rebalancing trades my model generates.

  • Current Choice: I have switched to Tiered Pricing (from fixed).

  • The Logic: This drops my UK minimums to approximately £1.20, saving 76% per trade vs. the £5.00 Fixed minimum. This is essential for keeping "drag" low on small position adjustments.

2. Automation & Permissions

I’ve found that the API requires a few specific "green lights" in the IBKR portal:

  • API Certification: Signed the Market Data API Acknowledgement.

  • Subscriber Status: Verified as Non-Commercial to keep data costs at retail levels.

  • Data: Currently using "Snapshot" data. I’m still evaluating if a full streaming bundle is necessary for daily rebalancing.

3. Execution Logic / Order Types

I’ve saved two distinct VWAP configurations in P123 to handle different levels of urgency:

  • Setup A (Passive/Rebate Capture): VWAP 1% / Add Liquidity: YES. My low-impact default. It attempts to never take liquidity to capture exchange rebates, though it requires price stability.

  • Setup B (Urgent Fill): VWAP 5% / Add Liquidity: NO. I use this when I need a faster fill, prioritizing completion over rebates.

  • Real-World Note: On a recent test order (AEP), the tighter settings didn't fill fast enough, and I eventually used a Market Order to establish the position.

  • Any others order types I should consider and set up?

4. Currency Management (Base USD)

Since my account is USD-based, buying UK shares creates a negative GBP balance (a margin loan).

  • The Math: On a $5,000 position, the interest is ~$0.73/day (at ~5.25%).

  • The Strategy: I perform a manual Currency Conversion for a $2.00 flat fee.

  • The Logic: The $2.00 fee pays for itself in just 2.75 days of avoided interest.

My Question for the Community: Anything else I should consider or think about while I am testing buying in various European markets and understanding the ins and outs before committing to a full EU model? I'm particularly interested in any "gotchas" regarding specific exchange rules or IBKR settings that I might have overlooked.

1/ Various fees for European exchanges, e.g. UK is 0.5% stamp duty cost per buy

2/ I’m based in the UK and IBKR doesn’t give me access to “ASX1” “segment” UK stocks on the AIM market. As far as I know, there is nothing in P123 which allows me to specifically exclude ASX1 stocks.

3/ The liquidity shown on P123 vs the liquidity available on IBKR for UK stocks can be very different, i.e. IBKR can be much lower.

4/ VWAP is not available on European stocks.

VWAP is indeed available for European stocks! Maybe not through P123, but there are only a few exchanges where it's unavailable (if I remember right, Sweden may be one). Just use Trader Workstation to place VWAP orders if you can't do so via P123.

A huge number of LSE stocks trade via auctions, which are conducted around three times a day (not sure exactly how many). Don't expect to see any fills between the auctions, and don't bother placing VWAP orders for those.

Don't order Norwegian stocks via IB. They use an alternative exchange rather than the main Oslo exchange and you'll end up paying enormous market impact costs even for tiny orders.

If you're using a retirement account, take dividend taxes into account. For US stocks you pay no taxes on dividends in a retirement account. But there's no refund for European taxes taken off a retirement account.

As zzebla points out, there is a 0.5% stamp duty on UK stocks that is paid only when buying, not selling. There are other, smaller stamp duties for other countries too.

I actually had some good experiences with Norwegian stocks on IB. Or at least, that is what I think right now (and thought so last couple of years).

For example, VEI (Veidekke ASA) under Other Reports - ‘Transaction Costs Analysis’, I see:

  • Orders / Trades / Qty: 1 / 1 / 579

  • Total Premium: 9,958

  • Arrival Price: 47.0 bps

  • vs Trade +1 sec: (15.7) bps

  • vs Trade +10 min: 0.0 bps

  • vs Close: (62.7) bps

  • vs VWAP: 0.0 bps

  • Commission: 4.98

  • Commission/Share: 0.0086

So roughly in line with VWAP.

Or have I been missing something all these years?

Some Norwegian stocks can be traded directly from Oslo but the rest via Frankfurt Stock Exchange (with limited liquidity). The same applies to Finish stocks.
