I like to be in sync with ‘professional traders’. Over the years I have learned how to, usually, tell how bullish the professionals are towards a market by how they do their buying. By using the Williams Professional Sentiment Index it is possible to arrive at a percentage of bullishness. When the index is high, I want to look at my other VantagePoint indicators and trade to the long side. On the flip side, you can use the Williams Professional Sentiment Index to identify when professionals are bearish and if VantagePoint indicators are in sync, a short position should be considered.
