Share Trading Simulator: A Weekly Routine That Builds Real Skill

A share trading simulator lets you buy and sell shares with virtual money, so you learn the mechanics without risking a single rand. Used well, it builds habits that last: a routine, a journal and strict position sizes. Used carelessly, it teaches the opposite. Here is a structure South African beginners can follow before opening a real account on the JSE.

What does a share trading simulator actually teach?

A simulator teaches the mechanics: order types, quantities, how a stop works, how fast a price can move. It shows volatility in rand terms instead of percentages. Above all, it gives you a place to build a process and test it over many trades.

What it cannot teach is the feeling of a real loss. Most simulators also fill orders at the price on screen and leave out costs that apply to real JSE trades, such as brokerage, VAT on fees and the securities transfer tax on purchases. Treat simulator profits as an upper limit, not a forecast.

South Africans have more options than most. Several brokers offer demo or virtual accounts with JSE shares, and the JSE Investment Challenge has given school learners and university students a virtual portfolio to manage for years. Games are another route. For an honest look at the strengths and blind spots of practice money, read what paper trading teaches and what it hides.

A weekly routine for your share trading simulator

Structure turns a simulator from a toy into a training ground. This cycle takes about three hours a week:

The schedule matters less than the separation it creates. You decide when calm, act when prices move and judge when the market is shut. Mixing the three is where bad trades come from.

How to keep a trade journal that teaches you something

A journal is the difference between practice and play. For every trade, record:

• The date, the share, buy or sell, and the reason in one sentence.
• Entry price, stop, target and position size.
• The rand amount at risk and the result.
• Whether you followed the plan, and how you felt at entry and at exit.

Every Friday, turn the entries into numbers. The most useful is expectancy: the average amount each trade makes or loses. Suppose 40% of your trades win an average of R1,500 and 60% lose an average of R800. Expectancy is (0.4 × R1,500) minus (0.6 × R800), which is R600 minus R480, or R120 a trade. You can be wrong more often than right and still come out ahead, provided the losses stay small. Then deduct realistic costs and see whether the edge survives.

Position size rules that survive real money

Position size decides how long you last. A common rule is to risk no more than 1% of the account on any single trade. Here is how to turn that into a number of shares:

1. Start with the account value. Say R50,000.
2. Apply your risk limit. At 1%, the most you can lose on this trade is R500.
3. Find the distance to your stop. Buying at R100 with a stop at R95 means R5 a share.
4. Divide the risk by that distance: R500 ÷ R5 = 100 shares, a position worth R10,000.
5. Check your cap. If no single position may exceed 20% of the account, R10,000 is exactly the limit, so the trade fits.

Two more rules complete the set. Keep total open risk below a ceiling, such as 5% of the account across all positions. And stop for the day after a fixed loss, so one bad session cannot turn into a bad month. A stop is not a guarantee, either: a share can open well below it after bad news, which is why the overall caps matter.

When to move from a simulator to a real JSE account

Move when the evidence says so, not when the simulator gets boring. A fair checklist:

• At least fifty journalled trades under the same rules.
• Rules followed on at least nine trades out of ten.
• Positive expectancy after realistic costs.
• A losing stretch you lived through without changing the rules halfway.

Then start small, with an amount whose loss would annoy you rather than hurt you. Your behaviour will change with real money, and that is the last lesson a simulator cannot give. Choose a provider authorised by the Financial Sector Conduct Authority (FSCA) as a financial services provider, and check the FSCA's warnings before sending money anywhere. Be especially wary of leveraged products such as CFDs, which are promoted hard on social media. Tax on share profits depends on your circumstances, and SARS may treat frequent trading differently from long-term investing, so check SARS guidance or speak to a registered tax practitioner.

Many South Africans also invest through tax-free savings accounts, unit trusts and ETFs. Those suit long horizons better than active trading, and the discipline a simulator builds serves both.

Simulator habits that cost money later

• Resetting after losses. If you can wipe the slate, you never learn to recover from a drawdown.
• Trading huge size. A position you would never take with real rands teaches nothing useful.
• Trading every day because it is free. Real costs punish overtrading, so build the restraint now.
• Revenge trades. Doubling up after a loss is cheap on a simulator and ruinous in a real account. Catch the impulse while it costs nothing.
• Practising only in rising markets. Your rules need to survive falls as well.

A game with consequences helps with the first two. In WallThrone your net worth decides your rank, so a careless week shows in the ranking, and a 0.05% commission on every trade makes overtrading visible. You can also hire traders and assign them capital, which turns sizing into a question of how much risk you hand to someone else. The biases behind revenge trading are covered in how psychology bends investing decisions.
