Am I very lucky or is it the market conditon?

I’m 24 I work full time as an accountant. I day traded 4 years ago but i was very impatient and kept selling as soon as i saw the stock price drop. I lost lots of money. However, now i’ve graduated from college and understand the way the market works. I’m using contrarian market principle at a more simplified and quicker approach. The principle says buy when a stock is turning low and sell when it eventually goes up. I buy when a stock plummets and sell after a short gain from a quick bounce in share price. I don’t sell untill it recovers! It hasn’t worked perfectly b/c i’ve had to wait up to 3 months once for a stock to get out of the red. I’m just looking to make a quick 0 a week of a 1-2% upside. What do you think about this strategy? Is this strategy only successful b/c of the high volume and volatility in the current market place? I’m using all my savings to trade and made about K this year mostly due to 3 windfall trades where i gained 10%. Should i continue with this strategy? Should i stop and leave my money in a bank? What was your experince of day trading? Is it like gambeling? lets not forget the high taxes i’ll be paying at the end of the year.
