Do your Due Diligence.

Always read up on the stocks you are intending to buy. look at the P/L, earnings ratio etc. Moomoo gives a very good detail summary of the details.

Trade at your comfort zone. Don't spend all your money on stocks. This is not a game. Read up Moomoo beginners classes and tips. Learn how to read the graph (MacD/RSI etc).

There are always friendly moomooers that are commenting in the comments section. Some may be informative but take it as a pinch of salt. Back to first point, DO YOUR OWN DD.

Always seek your dad's advice as ginger is spicier when old. Learned from the greatest. Happy Father's Day!
