Test the setup, not just the entry

Test the setup, not just the entry.

A real edge is more than where you get in. TradeStella lets you scale out in legs, book partials at each target and trail a runner, so your backtest measures the whole plan you actually trade, not a single all-or-nothing exit.

  • Scale out in legs at multiple R multiples
  • Book partials while a runner stays open
  • Trailing stops that follow price behind you
  • Realized R and open R tracked separately

Real market data, honest fills

Real market data, honest fills.

TradeStella replays genuine Yahoo market history, not a smoothed synthetic curve. When a single bar trades through both your stop and your target, it fills the stop first. No look-ahead, no flattering assumptions, just numbers you can trust before you go live.

  • Genuine Yahoo price history, bar by bar
  • Stop-before-target conservative fill order
  • No look-ahead: only bars you had are used
  • Slippage-aware so results stay realistic

Stop filled first

One bar touched your stop and your target. TradeStella assumes the worse fill, so your backtest never counts a win it could not have earned.
