The story of limit orders — I spent a whole day waiting for a price that wouldn't execute

When I first bought US stocks on Gate, I wanted to save a few cents, so I placed a limit order for NVDA at 224.5 (the current market price was 225.7).
As a result, I waited all day, and the stock price only dropped to 225.0 at the lowest, but the order didn't fill.
The next day, the stock rose to 226, and I had to buy at a higher price.

This was an expensive lesson: to save 0.1% in costs, I missed the buying opportunity and ended up paying a higher price.

Later, I changed my approach: if I am very optimistic, I buy directly at market price, not fussing over a few cents.
If I am moderately optimistic, I place a limit order slightly below the market price; if it fills, great, if not, I don't mind.

Additionally, limit orders have another use: splitting into multiple orders.
For example, if I want to buy 0.03 shares of NVDA, I can split it into three orders: 0.01 shares at 224, 0.01 at 223, and 0.01 at 222.
This way, if the price drops to 222, I buy in parts, averaging a cost of 223, which is lower than buying all at once.

Gate's limit orders are as convenient as spot trading — you can modify prices, cancel orders, and view order book depth.
I often place orders before the market opens because pre-market volatility is high, and sometimes I can pick up bargains.

But remember one thing: don't miss big opportunities just to save a little money.
If NVDA rises from 200 to 300, whether your cost is 205 or 210 doesn't matter much.
But the difference between "buy" and "not buy" is worlds apart. #分享美股交易赢英伟达股票
