literally most of demo trading account in big popular exchanges are the best way to go.
why? because the data is pulled from real price and not just made up data, so you can actually feel how the market is doing except you're just using fake money to trade around.
just find with the keyword binance demo account, etc. most of them allow you to set up demo account just to get the feel of trading. be sure not to click on scam links though.
I love real-time data on anything that I will be practicing because obviously it allows us to experience the real thing with of course without the fear of losing our own money. About the keyword, is that also find inside the trading platform such as Binance? That's cool because we can just click on them when we see them when we scroll but yeah, it is risky if it is seen else where. For our safety, we must visit the official site first and we need to check if it was properly spelled. Even without keyword or tags, they must have their own category that we can as well see. There must also be a search box where we can input what we are looking for.
