How Trading Platforms Work

The user layer

What you see — charts, order tickets, account dashboards — is the thinnest part of the system. It is also the most polished. Don't confuse interface quality with platform quality.

The matching layer

Once you submit an order, the platform either matches it internally against other clients (an internalised model), routes it to a liquidity provider, or sends it to an exchange. Each model has different implications for spread, execution speed and conflict of interest.

The settlement layer

In traditional markets, settlement is typically T+1 or T+2. In crypto spot, it is effectively instant. Derivatives use margin and mark-to-market processes. Settlement determines when, and under what conditions, your position is "real."

Fees, openly

• Spread — the bid-ask gap on the platform's quoted price.
• Commission — explicit per-trade charges, where applicable.
• Financing — overnight charges on leveraged positions.
• Non-trading fees — withdrawal, inactivity, currency conversion.

Many platforms emphasise one fee while quietly charging another. The total cost is the relevant number.

What this means for evaluation

When you read our BLUMBERG global review, the categories we discuss — order types, execution, fee structure — map directly to the layers above. Every serious platform evaluation traces the same path.
