The search term is "paper trade". Many online brokers offer this. It's good to know the mechanics of how to create and submit orders before you try it with real money. You can also find apps for that which aren't tied to a broker. You don't have to wait a full year if you use a "backtest", which works on historical data. There's software for that as well. Beware of future knowledge overfitting to noise though. Ultimately, it's best to analyze the historical data directly first, to prove the edge was there, before running a backtest. Training your intuition is a bad strategy. Markets are more random than you think they are, and this is becoming more true over time as markets become more efficient. You need a system.
