How do I use options chain to see strangle and straddle shifts?

This is another important trend that is underlying each stock. There are stocks that are in an uptrend and there are stocks that are in a downtrend. What really underscores this trend is the moving of the strangle range. If you see stock prices moving up but you also find the strangle range moving up it is a clear sign that the uptrend is being confirmed by the strangle traders. The reverse holds true in the case of down trending markets when the strangle range gradually moves downward.
