Using the H5 range as a reference helps traders understand where the market previously found limits of buying power and limits of selling pressure. These levels are often strong psychological areas, so when today's price re-enters or breaks through them, the market reaction tends to be more pronounced. If the price breaks through H5 resistance with momentum, it often indicates a continuation of the uptrend. Conversely, when H5 support breaks, downward pressure usually develops more easily.
