A second account at the same broker to keep strategies apart

Most brokers let you open more than one live account under the same profile. I think scalpers underuse this.

The main benefit is separation. If you trade two different approaches, say a London open breakout and a slower afternoon mean reversion, running them on one account mixes everything together. The equity curve, the drawdown, the history export, all blended. Two accounts give you two clean records without any tagging or filtering.

It also helps with risk. You can fund each account with a fixed amount and treat that as the full capital for that strategy. If one strategy hits a bad patch, the damage is visible and contained in its own account rather than quietly dragging down the other.

For EAs it removes a whole category of problems. No magic number clashes, no one EA closing the other's trades, no shared margin surprises.

There are some downsides. Funds are split, so margin per account is lower. Transfers between accounts are usually free at the same broker but can take time. Some brokers count account types differently, so a second account might not get the same commission tier. And you have more logins to keep track of.

Before opening one, ask support how internal transfers work and whether the new account keeps your commission tier.

Naming the accounts clearly saves a lot of confusion. Most brokers let you set a nickname or at least see the account type in the client area. Put the strategy name in there. When you're logged into MT5 with two accounts saved, the server and number are easy to mix up, and placing a trade for strategy A on the strategy B account defeats the whole point. Some traders also use different chart colour schemes per account so it's obvious at a glance which one is active. A small label in the corner of the chart window does the job too.

Account currency is a choice per account at many brokers, and that opens another option. If you trade mostly EUR crosses on one approach and mostly USD pairs on another, choosing the account currency to match each can reduce conversion effects on your profit and loss. It isn't a big deal for most retail traders, but it does make the numbers in each account easier to read, because the results aren't moving around with the exchange rate between your account currency and the pairs you trade. It's a small thing, but it removes one source of noise from the results.

Tax and reporting is simpler too in some places. When you need annual statements, having each strategy in its own account means each statement already lines up with one approach. It won't change what you owe, but it can make your own records cleaner and make it easier to answer questions if you ever need to explain the activity. Check the rules where you live, since some places treat several accounts at one broker exactly the same as one account and others ask for separate figures. A short email to a local accountant usually answers it.

A second account also makes a decent testing ground. Open a small one and use it only to try new ideas live with tiny size before they go anywhere near your main account. It's real execution, real slippage and real spreads, but the amounts are small and the results don't pollute the history of your proven approach. Once an idea has enough trades on the small account to judge it, you can decide whether it graduates to proper capital or gets dropped. Keep the size truly small so a bad run there never feels important.

Matching account currency to what you trade makes sense. One detail for anyone looking at JPY: some brokers offer yen accounts, and with one the profit on USDJPY or the yen crosses lands in yen directly. The flip side is that the account balance then moves against a dollar or euro view of your money, so the performance numbers look fine while your real wealth changes with the exchange rate. For keeping strategies apart, I would still choose based on the reporting currency you think in, and accept a small conversion on the pairs that do not match.

Is there any way to tell from the outside how a broker handles the flow? Not with certainty. The routing decision happens behind the server, and no trade confirmation will ever say which path an order took. Still, some patterns make people wonder.

Take a broker that hedges only some accounts. Would the winners get slower fills while the losers get normal ones? In a pure agency model, fills depend on liquidity and market conditions, with no reason to treat a profitable client differently from a losing one. If two accounts at the same broker trade the same instrument at the same moment and one shows consistently worse slippage, that is at least worth asking about, though a different account type or a different server could explain it.

What would a B-book look like from the outside? Possibly very tight and stable spreads on quiet pairs, fills that match the quote almost perfectly, and then odd behavior around large news where the broker has more to lose by holding the other side. Possibly nothing at all. A well run internal book looks the same as a good external one on a calm day.

Then there is the question of whether any of this is bad in itself. Internalizing flow is legal and common. The concern only starts when execution quality quietly depends on how well a client trades.

So maybe the better question is not which book an account sits in, but whether fills stay consistent across time, size and profitability. Consistency is something that can actually be measured.

Has anyone compared fill quality between a small account and a larger one at the same broker, and seen a gap that conditions alone could not explain?
