Hm, quite fascinating question. For entry you aren't obliged to wait 4-5 candles in case we are talking about H1 time frame. You can just conduct the analysis on a lower time frame like M15 and M30, if everything is clear to you and you understand that you can enter the deal, then open a position without a doubt. You should pay attention to the trend, if you see that there is a downtrend, then just draw the support and resistance zones and open the position. If they are unclear to you, you can wait until the level will be hit by the candles and hence you will be able to draw these zones. Just try and practice.
