For order flow traders who backtest

Backtest in TradeZella. Read the order flow in your own platform.

Backtesting order flow shouldn't mean typing timestamps all day

Two tools, two clocks

Your backtester shows the candles. Your order flow lives in MotiveWave or Sierra. Every step means finding the same minute in a second window.

Time zones get in the way

One chart says UTC-5, the other says New York. Get it wrong and you're reading the wrong hour's order flow without noticing.

It breaks your focus

Backtesting is about reps. Clicking through date pickers between every candle kills the flow you're there to build.

How it works

Set it up once. Then just backtest.

  1. 1

    Install Delta Bridge

    One installer adds the background app, the Chrome extension and the MotiveWave study. It starts with Windows and stays out of the way.

  2. 2

    Open your backtest

    Open a TradeZella session. Your platform turns replay on and jumps to the same candle.

  3. 3

    Step candles

    Every candle you step in TradeZella, your platform steps too, in under a second.

Features

Built for how order flow traders actually work

Exact time matching

Every step is checked against your platform's own replay clock, so it lands on the right candle, not just close.

Time zones handled

Delta Bridge knows how each backtester labels time and converts it for your platform, daylight saving included.

Hands-off

No mouse takeover, no windows jumping around. Delta Bridge works inside your platform while you keep backtesting.

Only when you're looking

Switch tabs or minimize Chrome and your platform is yours again. Replay normally whenever you want.

One switch

Sync on, sync off. A live status panel shows both clocks side by side and tells you the moment they match.

Your setup, untouched

Keep your templates, footprint settings, DOM and indicators. Delta Bridge only moves the replay clock.

Questions

Does Delta Bridge place trades or touch my accounts?

No. It only reads the replay date and time shown in your backtest and moves your platform's replay clock to match. It never places orders and never asks for logins or passwords.

Does it work on Mac?

Windows only for now, since MotiveWave and most order flow platforms run on Windows. Join the waitlist to hear when that changes.

What if my chart uses a different timeframe than my backtest?

That's fine. Delta Bridge steps your platform until its replay clock reaches the backtest's time. For a perfect match, use step sizes that line up with your chart's bars, like 1-minute steps on a 15-second chart.

Will it get in the way when I'm not backtesting?

No. It only syncs from a backtest tab you're looking at, and there's a sync switch to turn it off completely.

Is Delta Bridge made by TradeZella or MotiveWave?

No. Delta Bridge is an independent tool that works alongside them.
