In recognition of the impact SCT has had on my profitability as a trader, I am pleased to offer this modest extension to the method. I have always had difficulty recognizing A/D, so after much research I developed the algorithm represented by the attachment. It is simply the running sum for each consecutive bar of the magnitude of the downshadow minus the magnitude of the upshadow, colored red when the sum is positive and green when the sum is negative. As you can clearly see, it reasonably represents when limit order traders want to buy from you, which means you should buy, and vice versa. Prosper with this tool with my compliments to Jack and to Spydertrader for their efforts on behalf of all ET. And with apologies to Walter B. Gibson: "Who knows what evil lurks in the hearts of traders? The Shadows know!"
