Independent grid bot simulator

Replay your grid bot over real market history before you risk any money

Enter your range, grid count and leverage. GridReplay runs them minute by minute on real market data, with your exchange’s fees (Pionex, Binance, Bybit or KuCoin), funding and liquidation, and shows you what would actually have happened.

What you’ll be able to do

What your exchange doesn’t show you before you start the bot

Spot and futures

Test any configuration

Range, grid count, arithmetic or geometric, stop loss. See the grid profit separately from what the position gains or loses, and compare it with buy and hold.

Futures

See the real risk of leverage

Long, short or neutral, with the funding actually paid every 8 hours and the exact price at which the bot would have been liquidated.

Your history

Analyze the bots you’ve already run

Upload your exchange’s trade history and GridReplay rebuilds every bot: how much went to fees and funding, which ones were liquidated and what a different range would have done. We’re starting with Pionex; the waitlist decides which exchange comes next.

Why you can trust the numbers

Checked against 33 real Pionex bots

We rebuilt 33 real futures grids from their order history and replayed them in GridReplay. This is how close the simulation came to what really happened (see all 45 bots one by one):

96.6%of orders match on level and side (median).
30 / 33bots with a net result within ±5% (or ±1 USDT) of the real one.

Report: we put Pionex’s AI agents to the test

We applied the method suggested by their assistant Pai 200 times and asked their agent Quant how it runs backtests. Data, charts and methodology.

What it doesn’t do

A tool, not a signal seller

Who’s behind it

One person, not a fund or an exchange

GridReplay is built by Alejandro Rincón Rodríguez, from Spain. It started as a tool to review Alejandro’s own grid bots: the Pionex validation on this site uses that real account history, wins and liquidations included.

GridReplay isn’t paid by any exchange to recommend anything and doesn’t manage anyone’s money. Questions? Write to contact@gridreplay.com and Alejandro will answer personally.

FAQ

Worth knowing before you sign up

How do I know the simulations match reality?

Because we test against real bots and publish every result, order by order: 45 futures grids from a real Pionex account, liquidations included. It’s all on the validation page, including the bots that deviate and the ones we left out. Before launch we’ll extend it with bots from more users.

Do I have to share my API keys or account access?

No. Simulating only needs the bot’s parameters. To analyze past bots you’ll use the history your exchange lets you download; GridReplay will never be able to trade or move your money.

Will it tell me which bot to create or when to enter?

No. GridReplay is a simulation tool: you choose the configuration and see what would have happened. We don’t give signals or investment recommendations, and past results don’t guarantee future ones.

Which exchanges are supported?

Simulations use real Binance prices and the fees of Pionex, Binance, Bybit or KuCoin. History analysis starts with Pionex; the waitlist decides which exchange comes next.

How much will it cost?

There will be a free tier and a full version at about $7 a month. Everyone on the waitlist gets to use it for free during the beta, no card required.

What do you do with my email?

We only use it to tell you about the launch. We don’t sell or share it, and you can unsubscribe at any time. Details are in the privacy policy.

Would you pay about $7 a month for the full version?

We won’t charge you anything now. It just helps us decide what to build.
