When FX Replay may still suit you

FX Replay's Pro plan, with seconds-level data and unlimited sessions, suits traders who mainly practise manual setups bar by bar.

Backtests you can trust

AlgoBars backtests use only the data available at each moment and fill orders on the next bar, so a result reflects your rules, not hindsight. They show the raw price move, before spread and commission, so you see the edge of the rules themselves. Check each broker's spread with the broker spread map before going live.
