The guy's name is Marlyn not some gal name Marilyn and too bad he stopped blogging over a month ago. Yes, he was a good teacher and lucky for us he left his blog up for us to learn from. New stockfetcher users can see how one goes about writing filters then tweaking them for better results. http://filteringwallstreet.blogspot.com/

Modified version of my BASIC FILTER using MARLYN's crossover criteria.

Interesting...


P.S. someone should download that blog to preserve it... you never know when it may no longer exist... IT WOULDN'T BE THE FIRST TIME SOMETHING DISAPPEARS OFF THE NET!!

I found something MARLYN wrote:

"Never buy a stock unless you have two numbers in mind - both exits - one above the price you paid and one below. If you hold above the upper number be ready to dump if it retraces to your target and never hold below your lower number.

If you follow that simple approach you can buy any stock at any price at any time. Remember learning how to trade is learning how to lose - anybody can learn how to win - it's the losing that is troublesome.

If you adhere to that last paragraph and just apply some selection discipline you can make money in any kind of market - up or down."

Sounds like MARLYN just may believe:

"IT'S NOT WHAT YOU TRADE, IT'S HOW YOU TRADE IT"

Anyone know what a "BOB formation" is?

Not familiar with that term. A google search didn't return an explanation.

I wonder if MARLYN reads the SF forums???

Easy Swing Trading - The Filter Posted by Marlyn Trades

"I wrote a filter that will help find weekly cross overs. It is pretty simple and seems to work - at least to the point of getting candidates. After that you are pretty much on your own - the weekly filters don't back test well in stockfetcher."

Fetcher[
show stocks where close is between 15 and 35
and average volume(90) > 500000
and weekly open < weekly ema(21)
and weekly open < weekly ema(8)
and weekly open < weekly ema(4)
and weekly close > weekly ema(21)
and weekly close > weekly ema(4)
and weekly close > weekly ema(8)
and weekly close > weekly open
and chart-display is weekly
and add column weekly atr(10)
and sort on column 5

A New Way to Look at RSI(2) and ATR(10)

This was the lead paragraph of today’s economic blockbuster - Home building posted a small gain in April, but permits for future construction plunged by the largest amount in 17 years, a sign the nation's housing industry is still in a deep slump.

When is the best time to buy something? I’ll give you a hint “buy low - sell high.” That’s right – when it is hitting record lows and it is something that you are pretty sure will recover, eventually.

Today’s filter is a new one and once again is a very simple one –

Fetcher[
show stocks where close is between 15 and 35
and average volume(90) > 500000
and rsi(2) reached a new 4 week low
and atr(10) reached a new 4 week low
]



You really can’t get much simpler than that can you?

It tests very nice too both in the short term (4 day swing) and in the mid term (30 day trades).

Short term – 69% win rate, 2.30 reward/risk ratio and a 95% ROI that’s compared to an SPX ROI of 1.54% for the same period. In other words, the market was depressed when this filter was tested.

The net change over 20 and 30 days was 3.56 and 3.63 respectively so this filter has some legs as they say.

The interesting thing about this filter is that as I go back through the previous day’s selections it shows a significant number of wins. Sometimes it takes a couple of days, sometimes a few weeks, but eventually the stocks selected seem to turn up. The best selections however are those that have the highest volume and that are beginning to ascend on the day after the filter finds them.


=============

QT Code for BOB and Cross Over

A new reader asked for some code so here it is - once more I make no representations of this information - you use it at your own risk. I provide no guarantees - this is NOT an invitation to speculate in the stock market.

BOB

If bar low[1] < bar low[2] AND volume[1] > volume[2] AND bar open[1] >= bar close[1] AND bar open[2] >= bar close[2] AND bar low >= bar low[1] AND bar close > bar open AND ema(8) < ema(21) set color to “choice”


Cross Over 1 (for signal on the cross over bar)

If bar open < ema(21) AND bar open < ema(8) AND bar open < ema(4) AND bar close > ema(4) AND bar close > ema(8) AND bar close > ema(21) AND bar close > bar open AND bar close[4] < ema(21) set color to “choice”

Cross Over 2 (for signal on the bar after the cross over bar)

If bar open[1] < ema(21) AND bar open[1] < ema(8) AND bar open[1] < ema(4) AND bar close[1] > ema(4) AND bar close[1] > ema(8) AND bar close[1] > ema(21) AND bar close[1] > bar open[1] AND bar close[4] < ema(21) set color to “choice”

I use two cross over indicators - one on the bar and one after the bar. You don't have to do that.

You do have to select your own colors however. That's easy enough.

And, yes, there are differences between this version of cross over and the one I use on the daily charts. Most notably the moving average requirements are missing - I don't always play stocks that are below the EMA(90) and neither should you. I just prefer to filter for them because they have a lot of room to run.

===============================================


Keeping it Simple Revisited

One of my readers dropped a comment about a neat little filter I wrote a few months back based on something I read over at Larry Connor's site. The filter was simple as can be and the reader said that he was making good use of it.

So, in the interests of fairness - here it is again -

Fetcher[
show stocks where close is between 15 and 35
and average volume(90) > 500000
and close reached a new 10 day low
and close > ma(200)
and close < lower donchian band(20,4)
]




This throws a 64% win percentage in the current period (11/03/2006 - 03/05/2007). The short term ROI isn't bad -> 48% doesn't seem so high but when compared to the benchmark of 1.54% it is simply great.

So all you stockfetcher fans - here is one you may have forgotten - try it - I think you'll like it.

==================================================

From a reward/risk standpoint BOB v32x with 1.89 is far and away the best filter for use in the current time period. Here is that code.

Fetcher[
show stocks where close is between 15 and 35
and average volume(90) > 500000
and close 2 days ago < ema(8) 2 days ago
and close 1 day ago < open 1 day ago
and close 1 day ago is less than 1% < open 1 day ago
and close 2 days ago is less than .5% < open 2 days ago
and low 1 day ago < low 2 days ago
and volume 1 day ago is more than 20% > volume 2 days ago
and close > open
and low > low 1 day ago
and close 2 days ago < ema(8)
and close 2 days ago < open 2 days ago
]



=======================================
Just thought these should be saved just in case.

Did MARLYN ever post on the SF forum?!?

Found this on the MARLYN blog:


Disclaimer

Every few months I feel the need to write a brief to introduce myself and say what I'm about.

What I am is the promulgator of Rule 1 and Rule 1 is

- Nobody knows nothing - including me.



I say that frequently - especially after I've had a big win - having a big win does not make you better, nicer, prettier, or even smarter than anyone else - it just makes you a little better off than you were before the big win.

I say that frequently and it causes me to not watch CNBC or any other news that purports to be about the financial markets of the world. By the time you've heard it there it has already been acted on in the pits and you are now chasing the cow. Have you ever chased a cow? Don't - it just tires you out and annoys the cow.

I say that frequently and it causes me to try to learn something new every day. Yesterday I learned about bursitis - a fascinating disease unless you happen to have it in your hips - then it is just excruciatingly painful.

I say that frequently and it causes me not to have ads on my site - why have ads from people who don't know anything trying to sell you anything?

I say that frequently and I say it to you as a warning - if you take anything away from this site what I want you to take away is a thirst for knowledge, a thirst for learning, a burning desire to do something for yourself.

And now to adapt a thought from that old philosopher - Curly Washburn, "the only way you will become successful in the financial markets is to figure out the one thing that will make you a winner and then do that one thing over and over again."

Of course Curly's one thing was "honesty" and that's important too - above all things be true to yourself.
