there is one more thing you need to know , why we have to buy or what is strongest suggestive information is indicating for buy ? do you see Exhaustion ? or do you see high volume ? is it the level at which previously heavy buying was done and not tested after if formed ? what it is ??
in my view you should look for 4 Hour candlestick chart and then take a decision , if you are investing for buying then Check Higher time frame weather it suggests the area of demand or support for buying
