I have been testing various free stock market simulators lately, and honestly, the difference between what they offer today and a few years ago is huge. I used to think they were just toys for beginners, but I changed my mind when I started using them to test new strategies.

The first thing to understand is that not all simulators are the same. There is an important difference between traditional educational stock simulators and demo accounts offered by brokers (which exactly replicate how you trade with real money). It seems the same, but it’s not.

Educational simulators give you that feeling of investing, but broker demo accounts are something else: you see exactly the platform you would use with your money, the same spreads, the same tools. That’s why many serious traders use them before putting in real capital.

Regarding assets, basic simulators let you trade stocks, indices, and forex. But if you access a demo account from a decent broker, you have cryptocurrencies, CFDs, ETFs, commodities... everything you need to practice.

MyTrade surprised me quite a bit. It’s an Australian broker that has gained reputation in Asia, and its demo account is unlimited. That’s important because some brokers give you 30 days and that’s it. With MyTrade, you get $50,000 virtual, access from web or mobile, and you can switch between demo and real account whenever you want. That last part is key: you practice a strategy in demo and when you’re ready, you move it to real money.

MarketWatch also has a pretty complete free stock market simulator. It’s more educational, less sophisticated than a broker’s demo account, but works well if you want to start without complications. They give you access to analysis, watchlists, trader community... it’s like a simulator with context.

IG is one of the oldest brokers out there, listed on the stock exchange, and its demo account is serious. It uses MetaTrader, which is the industry standard. It’s not the most beginner-friendly platform, but if you want something professional, this is it.

HowTheMarketWorks is the classic. It has been educating students for years, and is very oriented towards schools and teachers. They give you $100,000 virtual to experiment with. It’s slower than others, but it’s good if what you’re looking for is real learning.

eToro is different because social trading is its strength. The demo account lets you see how copying other traders’ operations works, follow panels, all that dynamic. If you’re new and charts scare you, it’s a good entry point.

Now, there are things you should keep in mind. Virtual money sometimes makes you irrational. You take risks you would never take with real money because, after all, it’s fictitious. Also, in demo you have a lot of capital available (tens of thousands), but when trading live, you have less, so your decisions need to be more selective.

Another problem: some simulators are slow or inaccurate. That’s understandable because they are educational tools, but when you switch to real money, execution is different.

If you’re going to use a demo account, do it seriously. It’s not a casino. Follow the same discipline you would with real money, keep a record, analyze your decisions. The best practice is to combine demo with education: read, study, test in demo, repeat.

And here’s something that surprises many: professional managers and investment funds also use simulators before trading with real capital. It’s not just for beginners.

The truth is, today you have plenty of options to practice for free. The important thing is to choose wisely based on what you need: if you want to learn from scratch, look for something educational; if you want to test strategies before investing money, a broker’s demo account is your best bet.

If someone asked me what’s the best option to start, I’d say a free stock market simulator from a broker that allows you to switch between demo and real seamlessly. That way, you practice risk-free and when you’re ready, you move to real money without changing platforms.

The conclusion is simple: use these tools. You have nothing to lose, they’re free, and they can greatly improve your trading. The best traders I know still use demos to test ideas. Don’t underestimate the power of practicing correctly.
