I'm more of a longer timeframe trader, but what you want to do is get two timeframes. Look like in your case maybe a 5 min and a 30 min. Use the longer timeframe, i.e. the 30 min as your anchor/reference chart to determine the current 'longterm' trend you're looking at. MACD is theoretically a trend indicator whereas stochs and RSI are oscillators. Put the MACD on the 30 min chart, and as a rough plan, aim to trade only in the direction of the overriding trend, i.e. in the direction of MACD momentum. Use your 5 minute chart to take your signals on, so put the stochs on the 5 min. If the 30 min MACD is in a downtrend, you wait for the 5 min stochs to go near or into overbought extremes and then look for a short entry to get back in with the longer term trend.
That is a rough plan you can work with. That way, when you get the conflicting signals it's all good. MACD 30 min in a down trend and 5 min overbought. If 5 min is oversold, then you should be cautious about jumping on board the move as it maybe ripe for a retracement where you'd want to get in. Depends on your experience etc.
Also look for divergences. MACD 30 min in a downtrend, bearish divergence on the 5 min, big signal. Divergence on the 30 min MACD, the be cautious about jumping in until the divergence has played out or been unwound.
Good luck - hope anything here has helped.
