Trading using support and resistance with moving averages

Whenever the price crosses the moving up or down, in my anakysis I use chart of BTCUSD when the price crosses up the moving average on the 4H timeframe set Limit order to Long/Buy BTCUSD above the candlestick that pass through the moving average and set stop loss below it. I took my first profit at resistance of 12000 and rest when I saw confirmation of the Retracement move and waiting for confirmation to long or short now
