TapelineNQ replay, backtesting & trade journal

Practice the tape.
Keep every trade.

  • Real market data — second-by-second NQ from trade prints (Databento & IBKR, updated nightly), 16 years of 1-minute history.
  • Your backtests, saved — every session, trade, P&L and note, with a calendar of your results.
  • Live trading journal — log your real trades with R, contract, fees and notes, separate from backtests.
  • Resume after refresh — pick up a replay exactly where you left it.
  • Your account, every device — backtests, journal and chart settings saved to your private Tapeline account.
