[Tradewinds]

I've been using this indicator and really like it. It often shows buying or selling bias before the price move. And when it goes to an extreme, the peak or bottom is often very close. The close is rarely at an extreme, but the ratio often goes to an extreme, indicating that there is either a commitment to either buying or selling, or the buying or selling is maxing out, and you are at the extreme.
