Features

Bar-by-Bar Market Replay

Step through real historical price action one candle at a time. The chart only shows what you would have seen in the moment — no peeking at the future.

Trade Like It’s Live

Place entries, exits, stops, and targets on the chart exactly as you would in a live session. Every decision is yours — no bot, no automation.

TradingView Charts & Indicators

Practice with the same professional charting and indicators you use in live trading, so the skills you build transfer directly to real sessions.

Rulebook Integration

Attach your documented trading system to a session and check off your rules on every trade — turning your strategy from an idea into a habit.

Session Stats & Scoring

Every session is scored: win rate, profit factor, drawdown, and rule adherence. See in numbers whether your discretionary edge is real.

Adjustable Replay Speed

Fast-forward through quiet stretches and slow down when price approaches your levels. Compress weeks of screen time into a single evening.

No Hindsight Bias

Future candles stay hidden until you advance the replay, so you make decisions under the same uncertainty you face in live markets.

Real Historical Data

Replay any supported pair across the market history Gainium provides — bull runs, crashes, and long sideways ranges included.

Zero Risk, Unlimited Practice

Run as many sessions as you want without risking a dollar. Build the pattern recognition and discipline that only screen time can teach.

Why Backtest By Hand?

Automated backtests validate a bot’s rules. Manual backtesting validates the trader — your pattern recognition, your discipline, and your execution under uncertainty.

Compress Screen Time

Experience months of market conditions in a single evening. Replay speed means you rack up the reps that normally take years of live watching.

Kill Hindsight Bias

Scrolling a finished chart makes every setup look obvious. Hidden future candles force honest decisions — the same uncertainty you face live.

Prove Your Edge First

Session scores turn “I think this setup works” into measurable win rate and profit factor — before a single real dollar is on the line.

How a Replay Session Works

  1. 1

    Pick a Market and a Moment

    Choose the pair, timeframe, and starting date you want to practice — a trending run, a brutal crash, or the sideways chop that eats most traders alive.

  2. 2

    Attach Your Rulebook

    Load the trading system you want to drill. Your entry, management, and exit rules stay in front of you for every decision in the session.

  3. 3

    Trade the Replay Bar by Bar

    Advance the chart candle by candle and place your trades by hand. Speed up through the quiet stretches, slow down when price hits your levels.

  4. 4

    Review Your Session Score

    Get win rate, P&L, drawdown, and rule adherence for the session. Compare sessions over time and watch your execution improve where it counts.

Manual Backtesting vs. Automated Backtesting vs. Paper Trading

Three risk-free ways to test on Gainium — each answers a different question. Manual backtesting trains the trader, automated backtesting validates the bot, and paper trading confirms both in real time.

Frequently Asked Questions

Manual backtesting is the practice of replaying historical market data bar by bar and making trading decisions by hand, as if the market were live. Instead of a bot executing rules automatically, you decide every entry, exit, and stop yourself — building real decision-making skill against real price action, without risking money.
Automated backtesting tests a rule set: the engine replays your bot configuration against history and returns results instantly. Manual backtesting tests you: you step through the same history one candle at a time and make each decision by hand. Use automated backtesting to validate bot strategies, and manual backtesting to train and validate your discretionary trading.
Both are risk-free, but paper trading runs forward in real time against live prices — one day of practice takes one day. Manual backtesting replays history at the speed you choose, so you can experience months of market conditions in a single session. Many traders drill setups in the replay tool first, then confirm them in paper trading before going live.
Yes. The chart only renders candles up to the current replay position, so you cannot see what happens next until you advance the replay. This removes hindsight bias — the biggest flaw of eyeballing a historical chart — and forces you to trade under real uncertainty.
A rulebook is your documented trading system inside Gainium — the conditions that must be true before you enter, manage, and exit a trade. When you attach a rulebook to a manual backtesting session, you can check your rules on every trade you take, and your session results show how well you actually followed your own system.
Each session produces a performance summary including win rate, profit and loss, profit factor, drawdown, and rule adherence, so you can compare sessions over time and see whether your execution is improving.
You can replay the pairs available on Gainium’s supported exchanges across the historical data the exchange provides, on the standard chart timeframes. That lets you practice the exact markets and timeframes you intend to trade live.
No. Beginners use it to build screen time quickly, but experienced traders use it to drill a new setup, rehearse a market regime they struggle with (like ranging chop or high-volatility news candles), and keep their execution sharp between live sessions.
Yes. Practice trades and session results feed the same review workflow as live trades, so you can analyze them in the trading journal and spot the patterns behind your best and worst decisions.
