[amibroker] QRS Equivilent Scoring... was... PositionScore...



PureBytes Links

Trading Reference Links

Jitu,

The 'PositionScore Ideas' Subject is getting a little old. Let's
change it to QRS Equivilent Scoring.

To begin with, I want to reiterate what I stated earlier as it regards
my posting comparative backtest result stats. Here is a para-phrase
(if that is the right term):

"This backtest comparison is for illustrative purposes only. I make no
claims regarding these test results other than the AFL and Setup
criteria are identical for comparative purposes."

I am running my backtest against a 650+- stock watchlist.

This list is comprised of stocks whose avg daily trading volume
exceeds $25,000,000.

This 650+- ticker watchlist represents about 85-90% of the daily
dollar trading volume on all U.S. exchanges.

I exclude about 8000 other less active issues that DO have QRS ranking
figures, for the purpose of liquidity.

I refresh this list monthly.

This is a matter of personal preference... and whether you agree or
disagree with this approach, it maintains a level playing field for
the purpose of comparing different scoring methodologies. (It also
provides a very fast way to run successive backtests with different
parameters).

QRS values are available on 8,500+- stocks in my QP2 database.

When I run these backtests against the entire 8,500+- tickers, the
results are not as good as represented in my 650+- ticker watchlist.

I do NOT have slippage factored into the results that I am posting
here. The reason is that 'slippage' is a slippery subject indeed <g>,
and I don't have a method of measuring slippage that I am comfortable
with.

I have been trading this system for a few weeks, but not in the purely
mechanical fashion as reflected in the backtest. I am making a little
profit with it, but as much as I hate to admit it, a discretionary
side of me has been awakened and I'm overiding some aspects of the
pure mechanical system (which is not hurting me so far)... (but which
I expect could hurt me in the long run).

Once again, what I am posting is purely for the purpose of providing a
solid base for comparing QRS equivilent measurements.

Hope this answers your question.

Regards,

Phsst
