{"product_id":"v06-c02-pelleti-pdf","title":"V.6:2 (46-50): Pelletier on PDI","description":"Pelletier on PDI\u003cbr\u003e\u003cbr\u003eBob Pelletier is a distant but favorite figure to us at Stocks \u0026amp; Commodities. He's distant, residing in\nFlorida while we are in Seattle. He's a favorite because for years he has supplied us with data and\nsoftware for trading.\u003cbr\u003e\u003cbr\u003eWe've watched CSI grow from a small package that could run on Apples and Commodore 64's to a\nfull-service data vendor for major institutions. To us the interesting thing was that Bob himself, with the\nhelp of a band of programmers, was constantly developing new indicators and technical trading tools. His monthly newsletter often read like a trader's instruction manual.\u003cbr\u003e\u003cbr\u003eThis creativity seems to have reached its apogee when Bob's indicator, PDI (Probable Direction\nIndicator), was published. Then version II was published, then version III. These, together with CSI Stop\nand CSI Trend, were proprietary indicators that Bob made available as an add-on product to the data\nservice. Their distinctive feature was the use of probabilistic estimates of future price behavior. The\nprobabilities used were gathered from the time series itself, not an arbitrary \"parameter. \" An added\nlevel of sophistication was that the weighting accorded to any one estimate was adjusted as it performed\n or failed to perform well.\u003cbr\u003e\u003cbr\u003ePDI itself acts like an extraordinarily sensitive overbought\/oversold indicator (Figure 1), one which\nsometimes catches major moves well and other times bounces both with and against trends.\u003cbr\u003e\u003cbr\u003eNone of this material is disclosed so that you or I can learn from it or study it. You must play with it long\nenough to learn what the indicator is saying. However, the little that was disclosed persistently piqued\nour interest. We called Bob determined to pry all we could out of him. Here's the result.","brand":"store-traders-com","offers":[{"title":"Default Title","offer_id":52133776949617,"sku":"\\V06\\C02\\PELLETI.PDF","price":4.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0900\/3843\/6209\/files\/unnamed_ca4d321f-e8d9-4f7f-950c-c5c4cede4e84.jpg?v=1739652190","url":"https:\/\/shop.traders.com\/products\/v06-c02-pelleti-pdf","provider":"Stocks \u0026 Commodities","version":"1.0","type":"link"}
