One time I like scalping, but scalping will spend your time in front of the monitor screen 
you must focus on seeing each movement
the simplest way is to use Bollinger bands, MACD and RSI indicators. Time frame 5-15m

I use MACD and RSI only when first entry and closing a trade, playing safe between the RSI 30-70,
if the RSI is above 80 there will be Over Bought, and I decide to end my trade

But just focus on Bollinger Bands
Enter when the candle touches the bottom line on the Bollinger bands and sells touching the middle line or the upper line, don't miss this moment

One time I have posted about scalping (on my local board)
