Its true! Here are the details.\nAll pulse echos here must be a jillion ways to\ndetrend price data, and a good\nchunk of them have already been\nexplored in print. Given that, I\nhad to have a new and significant approach to the subject -\nand here it is. I discovered that a\ndetrended signal, combined with an optimum smoothing filter, can produce an extremely responsive oscillator-type indicator.\u003cbr\u003e\u003cbr\u003eI borrowed the concept of\nthis new detrending approach\nfor the markets from radar circuit designs, so to understand how it works, lets first take a\nlook at how radar works.\u003cbr\u003e\u003cbr\u003eTo refresh your memory, radar (which is an acronym, sort\nof, for radio detecting and ranging) works by transmitting a high-powered radio-frequency (RF) pulse and listening for the return\nechoes from various targets. RF energy travels at the\nspeed of light, and so the round-trip time for an echo\ncomes out to 12.4 microseconds per mile. The distance of the target from the transmitter is determined\nby measuring the time it takes for the echo to return.\nAfter sufficient time has elapsed so no more echoes\nare expected, the radar transmits another pulse. The\nprocess is repeated, and the time between pulses is referred to as the pulse repetition interval (PRI).","brand":"store-traders-com","offers":[{"title":"Default Title","offer_id":52134192120177,"sku":"\\V18\\C07\\060OPT.PDF","price":3.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0900\/3843\/6209\/files\/unnamed_04cce744-9dd0-4bc6-a5b3-43a94e75db2e.jpg?v=1739671137","url":"https:\/\/shop.traders.com\/products\/v12029opdetb","provider":"Stocks \u0026 Commodities","version":"1.0","type":"link"}
