yes, what owltrading said, use stops, More specifically, use trailing stops. you can specify them in $ or % amount. For example, if you have stock you bought at $10, and you think, I'm going to sell it when it reaches around the high, you can set the trail to around $0.50. That would immediately tell your stock to sell if the price goes down to $9.50. If the stock goes up to 10.50, the trailing stop would move up to $10.00. If the stock continues up to $14.00, your trailing stop would sell at $13.50. However, keep in mind this is real-time, and includes all the dips. So if your stock at $14 dips below $13.50, down to $13.20, then shoots way up to $1000 the next minute, you would have already sold your stock for $13.50, missing out on the $1000. So just be sure your trail is big enough to not sell to early, but small enough to not sell at that potential high point.

Use stops. Place your initial stop at wherever your acceptable loss is, then raise it as the stock goes up ( or down). Nobody gets all the profit. But if you can consistently keep your winnings @1.5 to 2 times your losses, you will make $ even if you only win 50% of your trades. I didn't consistently make money till I figured this out.

You are NOT "investing". You are "gambling".

Warren Buffett invests. He buys high quality and holds forever. You are playing Roulette and sooner or later you will lose all you "put into play".

Welcome to day trading and you have discovered the problem with getting rich quick. One thing you can try is to decide in advantage your selling trigger.

This posting lacks believability.

Not to brag, but I'm very precise at buying low, I'm able to buy low, really low, and time everything perfectly. But there's one problem, I'm terrible at selling high!

This is my typical investment, I watch a stock (sometimes for even months) I wait for the perfect timing, and I buy a bunch of shares (I play a numbers game, the more shares, the more return). Anyway, I usually get up a profit of about $40 - $100 per day. And then the stock drops and I lose money. For some reason (probably greed) Im just not able to push that sell button. And it cost me nearly $500 today!!!

I'm only 18 and I'm new to investing. I typically invest about $10,000 per investment. although I make a profit usually. I noticed I always miss the high points! I either sell way to early and make a tiny profit, or way to late and end up losing.

Can you please help me out.
