XAUUSD + NAS100 · MORE SYMBOLS BEING ADDED

A strategy tester for Gold and indices that runs in a browser tab.

Load a settings file or set the rules by hand, then run it over years of M1 history with spread and slippage applied. Session filters, partial closes, break-even shifts and trailing stops all behave the way they do on your terminal.

Two markets done properly, first.

We started with the two instruments traders test the most. Every tick is cleaned, gap-checked and stored in the cloud, so a ten-year run finishes while you watch.

From file to full results in four steps.

The same workflow you know from a desktop strategy tester, without the setup.

01
Drop your file in

Drag a bot file or a settings file onto the page. We read it, list every setting, and get it ready to run.

02
Pick market and dates

Choose Gold or NAS100, a date range and a starting balance. Set your lot size, spread and commission.

03
Watch it trade

The chart replays tick by tick with every entry, exit and stop drawn on it. Pause, rewind or jump to any trade.

04
Read the results

Profit curve, drawdown, win rate, best and worst days, and a full trade list you can download as a report.

Bot & preset import

Bring your own file or start from a proven template.

Settings sweeps

Test dozens of setting combinations in one run.

Visual replay

Every trade marked on the chart, at any speed you like.

Side-by-side runs

Compare two versions of a strategy on the same history.

PDF & CSV reports

Share a clean results pack with anyone.

Saved strategies

Keep a library of your tests and revisit them any time.

Everything the old desktop tester makes hard.

Same maths, same tick accuracy — without the 1990s interface.
