it's。impossible for them to mit significant amounts。of funds。after a trend has。been established。 The petition is。too intense and too many price concessions have to be made。 Consequently; we had to be prepared to anticipate trend changes。 In other words; we had to oppose the psychology of the marketplace and be prepared to buy。weakness。and sell strength。 It was。often difficult given the overall sentiment。 But it was。the only way to make large…scale mitments and to do so at propitious。price levels。 Trading discipline and objectivity were essential to thisunterintuitive approach。 TD Sequential was。the first trading method developed to acplish this。goal。 TD bo is。a related approach with more requirements。and greater precision。
Markets。advance and decline in a natural price rhythm that is。often definable。 Although the market does。not alwaysnform to this。price pattern prescription; even when it deviates; the price pattern is。still valuable because it forces。a trader to buy into price weakness。and to sell into price strength。
Determining Market Direction
Before mitting to a trade; you must define the market environment。 Is。the market vulnerable to an advance or to a decline; or is it locked into a trading ranger。 Much research and analysis。have shown that a simple basic。mathematical exercise; which we call TD Setup; will provide a clue to whether the market is likely to rally or decline。 By paring the market's。close on the current price bar with the close four price bars。earlier and then recording a series of similar consecutive price…parison closes; one can draw highly probable conclusions regarding future price behavior。 Specifically; by recording nine consecutive closes。lower than the close four price bars。earlier; a buy setup is。formed; and by recording nine consecutive closes。higher than the close four price bars。earlier; a sell setup is。formed。 Often; the pletion of these TD Setup series。is。associated with minor areas。of price exhaustion—particularly when the TD Setups。are properly price “perfected”。 Specifically; for a TD Buy Setup to be perfected and qualified for a short…term rally; either the low of buy setup price bar eight or the low of buy setup price bar nine must be lower than both lows。of buy price bars。six and seven。 If neither price bar eight's。nor price bar nine's。low meets。this。requirement; then you must await the first subsequent low that fulfills。this。requirement before the price 〃perfection〃 is。met。 Figure 2。1 illustrates just such a deferral。 Note in Figure 2。1 that once a low was。recorded that exceeded the lows。of TD Buy Setup price bars。six and seven; the market experienced an advance of a few trading days。
Conversely; in Figure 2。2; once a high was。recorded that exceeded the highs。of TD Sell Setup price bars。six and seven; the market experienced a decline of a few trading days; Granted; TD Setup price perfections。are often preludes。to speculative trades。of an indeterminable duration; nevertheless; their value may be to forewarn of a likely interruption of an ongoing trend。
Once the minimum requirement of nine consecutive closes。lower than the close four price bars。earlier is。recorded; the TD Buy Setup is plete。 Similarly; once the minimum requirement of nine consecutive closes。higher than the close four price bars。earlier is recorded; the TD Sell Setup isplete。 These setups。serve to provide the trader with the market's。likely trading environment。 Most often they are preambles。to countdown series that; once pleted; identify zones。of price…trend exhaustion。 TD bo is。designed to select only those price bars。of relevance and to ignore those that fail to adhere to rigid selection criteria regarding price relationships。 Specifically; it) addition to the setup phase; a subsequent and more onerous。process。is。followed。
The Buy or Sell Countdown
Once a TD Buy Setup of nine consecutive closes。lower than the close four price bars earlier is。recorded; the buy countdown process。begins。by referring back。to the first price bar of the buy setup and making the following parisons:
1。
The close of that price bar must be lower than or equal to the price bar's。low two price bars。earlier。
2。
The close of that price bar must be lower than the prior price bar's。close。
3。
The close of that price bar must be lower than the close of the prior countdown price bar's。close (note that the first price bar in the countdown series。has no prior price bar close)。
4。
The low of that price bar must be lower than the prior price bars。low。
Because countdown consists。of a total of thirteen price bars。that conform to the aforementioned prerequisites; or slight variations。of them; one can readily see that the conditions。necessary for countdown pletion are strict and exacting。 The same requirements; in reverse; apply to sell countdown。
Once a TD Sell Setup of nine consecutive closes。higher than the close four price bars。earlier is。recorded; the sell countdown process。begins。by referring back。to the first price bar of the sell setup and making the following parisons:
1。
The close of that price bar must be higher than or equal to the price bar's。high two price bars。earlier。
2。
The close of that price bar must be higher than the prior price bars。close。
3。
The close of that price bar must be higher than the close of the prior countdown price bar's。dose (note that the first price* bar in the countdown series。has。no prior price bar close)。
4。
The high of that price bar must be higher than the prior price bar's。high。
Figure 2。3; the Philadelphia Gold and Silver Index (XAU); illustrates。examples。of both TD bo low…risk。bottoms。and tops。 Beginning December 21; 2005; and continuing the next eight consecutive trading days; the minimum TD。Sell Setup requirement of consecutive price parisons。of closes。higher than the close four price bars。earlier was。fulfilled。 The numbers。for the sell setup appear above each price bar; and the series。stops。at nine because that is。the minimum number of consecutive price parisons。to plete a sell setup。 Upon pletion of the sell setup; countdown mences。 Unlike with TD Sequential; the countdown process。of TD bo refers。back。to the first price bar of the sell setup。 The lour prerequisites。described earlier are then applied to each successive price bar。
Figure 2。4 provides。a closer look at the same chart。 Note that the close of day one of the sell setup failed to fulfill qualifier No。 1。 It was。not higher than or equal to the high two price bars。earlier。 Consequently; sell countdown is deferred until possibly the next trading day。 The close of sell setup day two is。higher than or equal to the high two days。earlier。 Also; the close is。above the previous。day's。close; and the high is。above the prior price bar's。high。 The requirement of a close above the prior countdown close is。not applicable because there was。no prior countdown close。 Sell setup days three and four do not qualify asuntdown days。because both have down closes。and qualifier No。 2 requires。that the close be higher than the prior price bar's。close。 Sell setup days。five and six meet all the sell countdown qualifications。 Sell setup day seven does not qualify because its。close is。lower than the prior price bar's。close。 Sell setup price bars。eight and nine do meet the requirements of sell countdown。 At the time of pletion of sell setup; there are already five sell countdown days。 For the sake of parison; note that TD Sequential would only now begin itsuntdown process; but at the same time; the countdown requirements。for TD Sequential are less。restrictive—in fact; TD bo has。four times。the number of rules。that TD Sequential has。 Moving the process。forward; two days。after the sell setup ispleted; the sell countdown series。increases。to six; and the next four trading days。do not meet all the requirements。 January 13 and 14 do meet the requirements; and the countdown proceeds to seven and eight。 After a five…trading…day interruption; the countdown quickly records。five consecutive trading days。that meet all the countdown rules; and on countdown day thirteen the rally high is。recorded and price declines。
Price Exhaustion。and Reversal
TD bo is。designed to anticipate areas。of price exhaustion。 It is
