From a TA perspective looking at a half hourly chart to predict the next few days movement is a complete nonsense. Try looking at patterns, support, resistance, MACD, RSI, 3 way moving averages, momentum indicators, daily OHLC bars etc etc to determine the movement over the next few days. Total rubbish to use an intra day chart to predict the next weeks movement.
