Questions
Is this real money?
No. Traders is a paper trading simulator. Every order uses play money, so nothing here can gain or lose real money, and nothing is connected to a broker.
Where do the prices come from?
From Yahoo Finance’s public data. Most exchanges are about 15 minutes behind, and each price shows whether it is live, delayed or the market is closed.
Does it cost anything?
No. Traders is free with a Happy Light account.
Which markets can I follow?
Stocks and ETFs on many exchanges, major indices and cryptocurrencies. Prices from foreign listings are converted to dollars at the current rate.
Is it investment advice?
No. Signals and indicators are there to learn from. Nothing in Traders is a recommendation to buy or sell.
