A 3 day chart is very useful in terms of being able to see a major trend reversal. It eliminates the noise of daily or lower timeframe charts and shows the change in trend faster than the higher timeframes such as the weekly and monthly. Keep track of the candles and look for a higher high and higher low candle for the first signal. The USOIL chart above shows a sequence of 3 day candles that have lower lows and lower highs for the past 8 or more candles, clearly showing that the major trend is down. Short risk on oil is out of the question as long as there's no higher high and higher low 3 day candle. As soon as there's one, at least a minor change in trend can be anticipated and traders are likely to switch to short risk.
