Chart reading isn't a science, it's an art form!! They can be open to different interpretations. Real world events can affect the SP which makes the chart irrelevant.
I have just manipulated the trend line only on the exact same chart I posted a few mins ago.
As you can see the SP now has 4 bounces off that trend line & now a massive bullish break out!! Whose chart is right? junnnsonggg? My first chart? Or this one?
The Ichimoku indicators give a detailed picture of what the SP is doing (support, resistance, overbought, oversold). Most traders don't just use candle sticks & trend lines but several indictors to help them see what the market is doing. I use Ichimoku, MACD, RSI & Volume.
