Look beyond the highest number
Compare the rate for your instrument and account type. A higher figure for a different unit or account is not a direct comparison.
Example from API data
Axi lists 1.92 USD per lot for Forex on Standard and 0.64 USD per lot on Pro. Broker pages show the relevant account types and markets; values are generated from current API data.
