$451 in two days. Beginners luck?

$S&P 500 Index(.SPX.US)$ So I started playing with scalping back in Feburary. I Google “most volatile stocks today” and make a watchlist and add stocks from the list with high volume, usually $15 a share or under. I have RSI set to a length of 5. When a stock on my list drops below 20 RSI, I’ll throw some money at it. If it still drops, I’ll average down. When the share price is up by a cent or a few cents from my average buy in, I sell. I made dozens of trades in the last two days and only lost money on like three of them. I bought anywhere from a few hundred to a few thousand dollars per trade.
