[amibroker] An effective stopping methodology - 3BSMA and powerSAR stops

Hi All,

I have been searching for an effective stopping methodology for a 
very long time (since I began trading).  I experimented with several, 
like all kinds of MA based stops, Gann's Rule of Eights stop, ATR 
based stops etc., I finally may have found a good one.  It is based 
on the theory that there are essentially two types of markets:  
Trending and Trading Range.  An instrument does not start a new trend 
immediately after ending the previous trend.  It might go into a 
consolidation phase (Trading Range) before starting a new trend.  The 
problem is to time this start of a new trend.  Sometimes we have to 
wait for a long time indeed, thus if we enter the market too soon, we 
get whipsawed.  To solve this problem, I came out with the 
following:  Use a "mental stop" on day of entry at a reasonable 
distance from your entry point.  Either an ATR based stop or a pivot 
point support/resistance based stop would suffice and exit only after 
20 minutes has passed since your mental stop is exceeded and you are 
still losing.  Use a 3BSMA stop during the initial stages (from next 
session after entry when the start of a new trend is still not yet 
confirmed) in accordance with the principle: Cut your losses short.

Plot(MA(C,3),"MA3",colorWhite,1);

Once, a new trend has started (confirmed by LinRegReveral Indicator 
and/or Zig-Zag trend indicator) and powerSAR has also confirmed the 
new trend, use the following stop in accordance with the principle: 
Let your profits run.

Plot(scPowerSar(0.02,0.01,0.2),"PowerSAR",-16,8+16);

(You need AB's dll's to use this function)

SAR is the Stop and Reverse system developed by Welles Wilder.  This 
system indicates where one should exit a trade and simultaneously 
reverse positions.  It may also be coded to provide a stop for 
tomorrow's trading action.  This function does not work with 
Equivolume chart.  

This provides a systematic way to set a stop order.  The stops are 
changed daily and are adjusted to suit the market's conditions.  It 
also keeps you constantly in the market.  When one gets stopped out, 
you are also to initiate a trade in the opposite direction (In 
reality, you would already may have gotten a reversal signal and may 
be already trading it using a 3BSMA stop).  This is generally used by 
futures and forex traders.  Stock traders could of course short the 
stock however, one could also just buy stock and sell it without 
shorting it.  Then when the next buy signal occurs, jump in again.  
This can be quite useful during trending markets however, it is 
practically useless in trendless conditions (I use Dr. John F. Ehlers 
Squelch functions to distinguish between trending and trading ranges) 
or when the price is consolidating.  One can get whip-sawed and make 
several losing trades under these trendless conditions.

This function is inherently a trend-following study.  It increases 
the stop level each successive day until the 10th day that the market 
is still trending.  At this point, it raises the stop level 
proportionally daily.  This is due to the observed fact that 10-day 
runs are extremely rare.  These long runs do occur however they only 
occur around 5% of the time.  So this works magnificiently in trends 
and miserably in congestion or consolidation periods, but works well 
when combined with a 3BSMA stop during the initial stages (when the 
start of the new trend is not yet confirmed and you want a tight stop 
just in case the new trend did not start.  Doesn't mean that you were 
wrong in trading it, just that sometimes it takes a long time for a 
new trend to develop and most people don't have the guts to buy when 
everybody else is selling and sell when everybody else is buying and 
that is one of the reason most traders lose and ofcourse they may 
also lack patience and also adequate capitalization, money-management 
(PositionSize, MaxOpenPos, MaxRisk, PositionScore etc.,))

Any feedback appreciated.  TIA.

rgds, Pal
