The truth to the matter is Quah thought of a system and started trading his system and it seems to be profitable. That's all that really matters. Who cares about backtesting. He's forward testing his system. There are many systems and ways to trade everything and he has one he likes and trades. He's also got the balls to post his results and answer to the skeptics. My thoughts are ' who cares what anybody else thinks". It is working for him and that is all that matters.
It doesn't really matter whether it works for him or for anybody else. Those who can't stand discretionary strategies or tactics will hate it. Those who can't stand anything that can't be backtested will hate it. Those who can't stand anything simple because of their investment in software will hate it. Those who insist on knowing every logical detail of WHY will hate it.
What Quah's system does is
a. focus attention on what is generally the most volatile and the busiest time of the day
b. force the trader to make a decision rather than futz around with 27 indicators and 12 charts
c. force the trader to address price movement as is and take his losses and profits at certain points rather than get sucked into the mire of hope and fear
d. forget about setups and indicators and news and feelings and sentiment and many other sorts of nonsense, trading what one sees and not what one thinks
Given that, there are many variations that one could come up with and still meet these principles. And if some of them can't be backtested, so what?
