Look and works like junk tried on my Hotforex platform and once again got a proof that there is no better than simple but effective price action.


Some end of year thoughts on trading using priceseries *


Consciously, ‘PAv’ traders are categorically NOT able to trade with oscillators (/ indicators). (Note that ‘consciously’ part - because unconsciously every single one of them is creating and using ‘indicators’ in the background.)


Real oscillators traders can categorically NOT (consciously) trade with PA. (Note that ‘consciously’ part - because unconsciously every single one of them is attempting to process PA on the fly.)


Point is - Both modes are always going / functioning.


“Find your own way” zdo. Find out which one you are best suited for, make that one dominant and develop it that fully... Let the other one be recessive.


If you’re a PA trader, don’t fool yourself into total rejection of oscillators. And by the same token, if you’re an oscillators trader, don’t be swayed by the preaching of PA traders to completely exclude oscillators trading. Find out which one you are best suited for, develop that fully... and then you might be free to consciously include and accommodate certain aspects from the other one.




PA traders do notice and repeatedly announce an important ‘weakness’ of indicators. Stock indicators don’t ‘work’. :rofl:

Yep, statistically out the box at best they produce ( with ‘costs, a slightly negative) wash... ie the ‘sample runs’ where they outperform do not offset the ‘sample runs’ where they underperform, etc. **



The key word here is “stock”.


There are (only?) three ways to overcome this weakness of stock indicators.

1 ‘Skew’ the indicator calculations to match the ‘slope’ (and travel, etc) of the auctions.

2 Learn to ‘wetware skew’ the reading of the indicator to match the ‘slope’ (etc) of the auctions.

3 Type the auctions to know when and when NOT to apply an indicator


ie You got to know when and how to "harm squiggly lines" (sorry TRO for appropriating your apt phrase... :) )



Wishing all ya'll wonderful holidays and a happy solstice in exactly one minute !!!!







*instead of non price / fundamental / narrative information


**:haha: Unfortunately, PA traders can't go about as readily acknowledging the equivalent real world statistics of 'out the box' PA... ie don't get it that both modes are always going / functioning.

      MACRO EVENTS & NEWS OF 24th April 2018.

      FX News Today

      European Outlook: Asian markets moved mostly higher overnight, following on from a positive session on Wall Street and amid ongoing USD strength with a weaker Yen underpinning a 0.75% rise in the Nikkei. The Hang Seng is up 0.94%, the CSI 300 rallied 1.75% amid speculation that the government is considering easing some policies put in to limit the credit boom. The absence of any negative news on the trade front seems to have given stock markets some breathing space and U.S. futures are also up in tandem with U.K. futures. Oil prices are also up and the front end Nymex future is trading at USD 69.14 per barrel. For now though bonds are getting a boost and stock markets are also higher, with most European futures posting gains in tandem with U.S. futures and after a positive session in Asia. Today’s calendar focuses on confidence data out of France, Germany and the U.K.. The U.K. also has public finance data and Germany auctions 2-year Schatz notes.

      FX Update: The dollar posted fresh highs against the euro and yen, and many other currencies after a bout of demand in Asia, which extending a broad rally the greenback has been seeing against for over a week now. The narrow trade-weighted USD index (DXY) posted its highest level since the first week of January, at 91.07. EURUSD logged a 10-week low at 1.2184, though euro demand has subsequently fuelled a rebound to the 1.2220 area. USDJPY lifted for a sixth consecutive session, making a 10-week high at 108.87. EURJPY is also firmer, though has so far remained below the two-month high it saw last week. The gains in USDJPY have been concomitant with the U.S. T-note yield nearing the 3.0% level, which has been generating headlines, which comes with the BoJ continuing to peg JGB 10-year yields near 0.0%. The Nikkei 225 closed 0.86% for the better, more than reversing the moderate loss seen yesterday. North Korea’s Kim said that he would be willing to accept IAEA inspections of nuclear facilities.

      Charts of the Day

      Main Macro Events Today
        German IFO – The German Ifo business confidence indicator, due Tuesday, comes in a new format this month, which includes the services sector now. For the new indicator a dip is expected to 102.8 from 103.2, and a decline in the expectations reading to 99.5 from 100.1 in the previous month. However, after the better than expected PMI readings there is a bias to the upside to the numbers. In any case, we don’t expect the April round of survey indicators to really change the outlook for the ECB, which is seen on hold this week, with officials seeing scope to leave the final decision on the future of the QE program open until July, when the risks to the global outlook may have become a bit clearer and the decision is becoming urgent. UK Public Borrowing – Expectations – at 1.6B pounds from -0.272B pounds last month. US Consumer confidence – likely declined to 126.0 in April, from March’s 127.7. US New home sales – expected to rise to 0.630 mln in April from 0.618 mln in February. Support & Resistance Levels
