Yes i do experienced that day trading and i get quick profit but not so big if i saw that market up i will sell it even i get a small profit. Then i will buy back again if the price will goes down.
That was your luck. Dont think over and over about that. Sometimes, your skills handshakes with evil and you see some downstream about you. Right in your case, day trading must be done with much bigger confidence. You must know that profits and losses can be equalized in numbers so you must be ready for losses as well in day trading. However if you go for long term holding, you may better get way from such stuff.
