Latency
Define the measurement endpoints. Platform display, client-to-server round trip and order acknowledgement are different timings and should not be mixed.
Same protocol, comparable samples
Forex Broker Latency & Slippage Comparison
Test execution evidence without relying on unexplained speed claims. Record latency distribution, signed slippage and rejected orders for the same instrument, order, location and market conditions.
Slippage
Compare requested and filled price using signed pips. Separate favorable and unfavorable fills instead of reporting only the worst observation.
Tail behavior
A median can hide slow outliers. Record the 95th percentile when the sample and timing method support it.
Rejections
Count failed or rejected attempts beside completed orders, and document order type, size and the returned platform message.
Test environment
Demo and live execution are not interchangeable. Keep account environment, server, client location, connection and platform version with the result.
Market conditions
Session, liquidity and scheduled news can dominate a small test. Repeat the protocol across comparable windows before drawing conclusions.
Forex Broker Execution FAQ
Which forex broker has the lowest latency?
There is no universal answer. Observed latency depends on the broker entity and server, client location, network route, platform, account and measurement method. Compare brokers only under a documented protocol.
How do I compare forex broker slippage?
Use the same instrument, order type, size and market window. Record requested and filled price for every attempt, express signed slippage consistently, and keep favorable, unfavorable and rejected outcomes in the sample.
Is demo execution the same as live execution?
No. Demo infrastructure, liquidity simulation and order handling can differ from a live account. Label the environment and do not treat demo observations as proof of live execution quality.
How many orders are enough for an execution test?
One or a few fills are not a stable estimate. The useful sample size depends on variability and the question being tested; preserve the raw context and repeat comparable tests rather than relying on a universal threshold.
Does this tool rank forex brokers?
No. It stores user-entered observations and calculates only the rejection rate for the recorded sample. It does not independently measure brokers or identify a best broker.
