FxBacktest VS Blindgrade

FxBacktest's answer

Beginner traders who are looking for a good backtesting tool to analyze their strategies.

Blindgrade's answer:

Newer and intermediate traders who want to get better at trading without risking money. Most are crypto traders who have watched tutorials and want repetitions with feedback before they trade live. It also suits experienced traders who use replay tools and want to check whether their reads hold up when they can't recognise the chart.

HTML JavaScript TypeScript CSS Python MQL5 FxScript (custom made in app language)

Blindgrade's answer:

TypeScript, React, KlineCharts for the charts, Node.js with Fastify, and PostgreSQL. The live AI mentor runs on large language models. Every number it quotes is measured by Blindgrade's own trading engine, not written by the model

FxBacktest's answer

The chart is not just already made from another source, but our own made one. We made the bar replay, position sizing, trade entering and analytics easy to understand and super comfortable to use. Our analytics are a lot and the user can see where his strategy is leaking from a lot of different angles.

Blindgrade's answer:

Blindgrade hides the ticker and the dates on every replay. On other replay tools you pick the chart, so you often know how it ends: if it's Bitcoin in March 2020, you know the crash is coming. On Blindgrade you trade real historical candles without knowing what they are, so the only thing you can trade is what's on the screen. Each round is graded on your process: entry, size and where the stop went, not just profit. A live AI mentor marks habit-level mistakes on the chart while the candles are still playing. It sees only what you see and never tells you which way to trade.

We have a lot to offer on our both Pro and Ultra plan. But beside that our Free plans offer a lot of stuff also - 3 free sessions, all symbols unlocked on all timeframes, free manual trade journaling, free live trades journaling in app and a lot more.

Blindgrade's answer:

Replay tools like FX Replay and TradingView's Bar Replay are good for backtesting a strategy on a chart you choose. Blindgrade is for practising the decision itself, without hindsight to lean on. It runs in the browser with no install. The daily chart needs no account. A free account gets 15 practice rounds a week, with the AI mentor on 3 of them. Pro is $79 a year, less than most replay subscriptions charge for a few months. It adds unlimited practice, the mentor on every round, replay of any symbol from any date (blind or not), and full analytics.

FxBacktest's answer

A lot of tools just offered a chart to replay and a simple PnL analytics, and having almost no free data to backtest on. We spotted that and made a comfortable tool to use.

Blindgrade's answer:

Blindgrade is built by a solo developer and trader. Practising on replay kept running into the same problem: on a chart you can identify, you already half-know the ending, so a good trade proves nothing. Blindgrade started as a daily mystery chart, the same hidden chart for everyone each day, in the style of Wordle. Practice rounds came next, then grading on process, then a live AI mentor. It has been in public beta since September 2026.
