How to practise with this
Clicking buy and hoping teaches nothing. The value is in running a proper process on a chart where you genuinely cannot know what happens next.
- Read the chart first. Is there a trend? Where has price repeatedly turned? Mark those levels mentally before doing anything.
- Write down all four numbers (entry, stop, target, size) before you click. If you cannot fill them in, there is no trade.
- Size off the stop. A stop-out should cost about 1% of your equity. On $10,000 that is $100, so a $2 stop distance means 50 shares.
- Enter the stop in the box. The simulator will honour it automatically, which removes the temptation to move it.
- Advance day by day and let the position resolve without interference.
- Review in R. Every loss should be close to −1R. Losses larger than that point at the process, since the market only ever does what it does.
What a simulator can and cannot teach you
| Teaches well | Cannot teach |
|---|---|
| Order mechanics and position sizing | The fear of real money moving against you |
| Reading trend, levels and candles | The urge to revenge trade after a loss |
| Honouring a stop | Holding through a genuine drawdown |
| Thinking in R multiples | Slippage, spreads and partial fills |
| Patience: waiting for a setup | The temptation to over-size after a win |
About the price data
The chart is generated, not historical. It uses a random walk with shifting volatility and trend regimes, the standard statistical description of how prices behave. That is a deliberate choice: you cannot recognise the stock, cannot look up what happened next, and cannot pattern-match from memory. Every decision has to come from the chart in front of you.
It also means patterns here behave the way patterns behave in reality: sometimes they work, sometimes they fail, and there is no hidden signal to discover. That is the honest lesson, and it is the reason risk management matters more than pattern recognition.
Before your first session, read the chart-reading guide and the candlestick pattern reference. Then let the position size calculator set every position.
Frequently asked questions
What is a stock market simulator?
A simulator lets you practise trading with fake money against price data, so you can learn the mechanics of entering, sizing and exiting positions with nothing at risk. This one generates its own price series, so you can trade an unlimited number of scenarios straight away without waiting for real days to pass.
Is this simulator using real stock prices?
No. It generates a synthetic price series using a random walk with volatility and trend regimes, the same statistical model used to describe real price behaviour. That's deliberate. You can't recognise the chart or look up what happened next, so every decision has to come from the chart in front of you.
Does paper trading help?
It helps with the mechanics: order types, position sizing, reading a chart, keeping a journal. What it can't reproduce is the emotional pressure of real money, which is where most traders come unstuck. Treat it like a flight simulator. Excellent for procedure, incomplete for nerve.
How should I use this to practise?
Decide your entry, stop and target before you click buy, then size the position so a stop-out costs about 1% of your account. Advance day by day and honour the stop when it's hit. Your goal is to finish with every loss close to 1R. That's the habit that matters, and posting the biggest number is a different game.
