Good question!I don't know how much the EOD candle can depict the beginning of the next day.A "hammer" candle usually shows that the buyers staved off the sellers in that 5 minute period.On a longer 6 month chart a hammer may indicate a bullish reversal pattern if it forms on a down trend.A hammer that formed in a 5 minute period at the EOD probably has little significance to tomorrows opening.
