If you already hold a couple of ETFs on Trading 212 and you are tired of placing the same orders every month, Pies are the feature you have been looking for. A Pie lets you define a target portfolio once, then feed money into it on a schedule while the app buys fractional shares to keep your holdings near the weights you set. It is genuine set-and-forget investing, and it is commission-free.
The honest answer up front: Pies are one of the better automation tools available to a European retail investor, because they solve the two things most people get wrong on their own, consistency and rebalancing. But they are only as good as the portfolio you put inside them, and there is one currency-conversion detail that quietly costs you money if you ignore it. I use automation in my own investing precisely because it removes the temptation to tinker, so let me show you how Pies work and where the traps are.
What a Trading 212 Pie actually is
A Pie is a named basket of investments with target weights that you choose. You might build a Pie called “Core” that is 90% a global all-world ETF and 10% a bond ETF. Each slice has a percentage target, and the app shows a live pie chart of how your actual holdings compare against those targets.
Methodology: this guide applies our broker rating methodology, from safety-of-assets checks to total-cost math.
The important mechanical detail is that Trading 212 supports fractional shares. If you put €50 into a Pie split across three funds, the app buys tiny fractions of each so your money is fully invested in the proportions you asked for. Without that, small-sum automation would be impossible, because a single share of a popular accumulating ETF can cost well over €100. For more detail, see our guide: Trading 212 API.
You can hold multiple Pies side by side, for example a stable core Pie and a small satellite Pie for a thematic bet you want to keep contained. That separation is genuinely useful for discipline. I would rather someone quarantine their speculative money in a clearly labelled 5% Pie than let it leak into their main portfolio.
How AutoInvest works
AutoInvest is the engine that makes a Pie run on autopilot. You set a recurring deposit, say €200 on the 1st of every month, and direct it into a specific Pie. On the scheduled day the app buys across the Pie’s slices. Crucially, it does not split the money blindly by your target weights: it directs new money toward whichever slices are currently underweight, nudging the Pie back toward its targets every time you contribute.
That behaviour is the quiet superpower here. Traditional rebalancing means selling your winners to buy your laggards, which can trigger tax and always feels psychologically hard. Rebalancing with new contributions sidesteps both problems: keep feeding the Pie and it self-corrects without you ever selling a thing. Having the app do this removes the one step most people skip.
You can fund AutoInvest from money already in your account, or set up a recurring deposit so the whole chain runs untouched. Frequencies run from daily up to monthly, but for a long-term ETF investor monthly or twice-monthly is plenty. Daily contributions add nothing but noise.
How rebalancing works
There are two ways your Pie stays on target. The first, covered above, is automatic when new money flows in. The second is a manual “rebalance” button, which sells the overweight slices and buys the underweight ones in one move. That involves selling, so in a taxable account it can create a capital-gains event depending on your country’s rules. Check how your local tax authority treats disposals, and verify your position with a local tax adviser if unsure.
My preference is to let contributions do the rebalancing and avoid the manual button unless a slice has drifted a long way from target. For most people investing a fixed amount monthly, the Pie stays close enough to its targets that manual rebalancing is rarely necessary. Our guide to ETF portfolio rebalancing strategy covers when drift actually matters.
Setting up your first Pie, step by step
Assuming your account is open and verified, here is the sequence. If you have not funded an account yet, our walkthrough on how to buy ETFs on Trading 212 covers the basics. For more detail, see our guide: Plum vs Trading 212.
1. Create the Pie and add your funds
Open the Pies section and start a new Pie. Search for the ETFs you want and add each one as a slice. When you search, you will often see the same fund listed on several exchanges in different currencies. Pick the line quoted in your account’s base currency wherever possible, for reasons I explain in the next section.
2. Set your target weights
Assign a percentage to each slice so they sum to 100%. Keep it simple. A single all-world ETF at 100%, or a two-slice split of global equity and a bond fund, is a perfectly respectable Pie. You do not need eight slices to be diversified when one broad ETF already holds thousands of companies.
3. Turn on AutoInvest
Enable AutoInvest on the Pie, choose your amount and frequency, pick the funding source and confirm the schedule. From here the app handles the buying, the fractional splitting and the contribution-based rebalancing for you.
4. Set a review cadence, not a watch habit
Put a reminder in your calendar to glance at the Pie once or twice a year, not once a day. Automation only works if you leave it alone.
The FX fee trap you must avoid
This is the single most important practical tip. Trading 212 applies a currency-conversion fee, roughly 0.15%, whenever a trade settles in a currency different from your account’s base currency. Buy a USD-quoted line of an ETF from a euro account and you pay that fee on the way in and again if you ever sell. Inside a Pie that drips money every month, that small percentage on each contribution compounds into a meaningful drag over the years.
The fix is simple and free. Most popular UCITS ETFs are listed in euros on Xetra and in pounds on the London Stock Exchange, so choose the line quoted in your account currency. Same fund, same holdings, no conversion fee. Our comparison of Trading 212 fees for ETF investors breaks down where these costs appear. Treat all figures as 2026-vintage and approximate, and confirm the current rate on the official page before you rely on it.

Good Pie design: simple beats clever
The temptation with Pies is to over-engineer. The interface makes it so easy to add slices that people end up with a ten-fund Pie that overlaps with itself, costs more in blended fees and is harder to reason about. A global all-world ETF already spans developed and emerging markets, large and mid caps, across thousands of holdings. Bolting on a US tech slice and a separate S&P 500 slice mostly double-counts what you already own.
My rule is that a good Pie has one to three slices, each with a clear job: a global equity core doing the heavy lifting, an optional bond or cash slice sizing your risk to your timeline, and an optional small satellite for anything speculative. If you want help choosing the core fund, the free UCITS ETF comparison tool lets you line up candidates on fees and structure before you commit.
Here is how Pies with AutoInvest stack up against a traditional European broker savings plan, the main alternative for automated monthly investing.
| Feature | Pie + AutoInvest | Broker savings plan (TR, Scalable) |
|---|---|---|
| Commission on ETF buys | Free | Usually free on the plan menu |
| Multi-fund basket in one order | Yes, many slices | One plan per fund |
| Rebalancing on new money | Yes, automatic | No, plans run independently |
| Fractional shares | Yes | Usually yes |
| FX cost | ~0.15% on non-base lines (avoidable) | Often none in EUR |
| Best suited to | A multi-fund portfolio kept in balance | A one or two-fund plan |

What I’d do
If you are already on Trading 212 and want a hands-off portfolio, build one simple Pie with a global all-world ETF as the core, add a bond or cash slice only if your timeline needs it, choose the euro or sterling line to dodge the FX fee, and switch on a monthly AutoInvest. Then genuinely leave it alone. That single decision, made once, beats years of well-intentioned tinkering. The people who do best with Pies are the ones who resist adding a fifth slice every time they read a hot take.

Frequently asked questions
Q: What is a Trading 212 Pie?
A: A Pie is a custom basket of ETFs or stocks with target weights that you set. Trading 212 uses fractional shares to split your money across the slices in the proportions you chose, and shows your holdings against your targets as a live pie chart. You can run several Pies at once.
Q: How does AutoInvest keep my Pie balanced?
A: Each new contribution is directed toward the slices currently below their target weight, so the Pie rebalances with fresh money rather than by selling. That avoids triggering a taxable disposal. As long as you keep contributing, the Pie self-corrects toward your targets over time.
Q: Are Trading 212 Pies free to use?
A: Yes, buying ETFs within a Pie is commission-free, and AutoInvest carries no separate charge. The one cost to watch is the roughly 0.15% currency-conversion fee that applies when a trade settles in a currency other than your account’s base currency. You avoid it by choosing the fund line quoted in your own currency, and you should verify the current rate on the official page.
Q: How do I avoid the FX fee inside a Pie?
A: When you add an ETF, pick the line listed in your account’s base currency, for example the euro-quoted line on Xetra or the pound line on the London Stock Exchange. It is the same fund with the same holdings, so there is no downside, and you skip the conversion fee on every monthly contribution. This matters more in a Pie because the cost would otherwise recur on each drip.
Q: How many funds should a Pie contain?
A: Fewer than you think. A single global all-world ETF already holds thousands of companies across developed and emerging markets, so a one to three-slice Pie is usually all you need. Adding many overlapping slices raises your blended cost and makes the portfolio harder to manage without improving diversification. A clear core plus an optional bond slice is a solid design.
Q: Can I move my Pie to another broker later?
A: You are not locked in, but fractional shares generally cannot be transferred in-specie and may need to be sold, which can be a taxable event depending on your country. Whole-share holdings can often be transferred where in-specie transfers are supported. Check the rules and any tax implications with your local tax authority or adviser before you move.
