Hi Dimitris,
Would you mind explaining in simple English what
you have here. I mean what is the modus operandi of the system, the formula is
above my understanding. Why shouldn't it apply to any stock, with buy
only trades, for me? Is the formula as is applicable, etc.
All the best and TIA
Herbert

Some details:
The system is Short since Dec2.
It will cover and buy again in 7 bars.
The last 4 trades are profitable.
Dec16 was the 9th inspection day, the [25,28] combination is
again the timing preference for the next 17 bars.
[25,28] is the top combination for a 5th period, it is quite
successful.
[33,28] is ready to replace [25,28] , if the rhythm needs
some change.
[An intelligent system should always take care of the
succession...]

[33,28] and its harmonic hybrid [16,28] are the probable
successors of the long-time champion [25,28]

What could we do not to miss the move ? Here is the
elementary AI proposal:
The first significant ^N225 trough was on Jan31, 2003 and
the very next significant peak was on Feb17.Suppose we follow this pattern
and then buy every x1 days after the first buy and sell every x2 days after
the first sell.By the end of the first 6 months we try to learn the rhythm
of the market and trade it for the next 6 months.The initial rhythm may
need corrections as the market changes, inspections every 15-20 days are
necessary.The results are interesting:There were 3 main rhythm
combinations [x1,x2], the [29,24] for 34 days, the [26,33] for the next 34
days and, finally, a potential combination [25,28] was detected around mid
September and it is valid untill now.Another important issue : The system
"understood" around mid July that x1 should be < x2. It means buys
should be more frequent than sells, a characteristic of bullish markets
[the more you delay a Sell, the more part of the bullish trend you
enjoy...]The black [29,24] equity line was a nice solution up to the end
of July, the white [26,33] up to the middle of August.The red [25,28] was
the most tenacious all year long.The trading parameters are
