How To Use History To Create A Solid, Single Stock Trading System

Posted December 22nd, 2010 by Trading Systems | No Comments
Welcome Back!

We’ve all scanned charts and seen graphs of the “one that got away”.  Don’t despair.  I’m going to show you a way to find entries and exits for single stocks that are starting trend.

They say, history repeats itself.  In trading, that is very true.  Each stock has a personality of it’s own.  Learn the quirks and it’s possible to trade a single stock for a long time, year after year.

And yes, I’m speaking from experience.  I traded AAPL (Apple) for many years.  My confidence was so great that I even owned AAPL LEAPS.

This technique is very logical, simple, and effective.

Find a stock that is in a stable uptrend.  I’ve chosen APKT (Acme Packet).

This is a daily chart of APKT.  The stock has risen from $10 to nearly $60 in less than a year.  The move was a very steady rise.

When I find a stock that has started to trend my first thought is finding the best entry and exit.

To do this I want to look at some history.

The question I want answered is, “how did this stock trend in the past?”

  • Find a prior trend and make some notes about price action.

There are three up trends on this compressed daily chart.  That should give plenty of study material to make some good observations about how to trade APKT.

Notice the boxed area on the chart.  I don’t consider this a valid area to study.  Price made an enormous gap up and then leveled off before declining.  That is not a trend.

A closer look at the first arrow in mid-2007  follows.  The chart has the following indicators: a 20 simple moving average (blue) and a 50 period exponential moving average (red).  Both MA’s are on the price bars.  There is a 20 simple moving average on the volume bars.

The area within the circle is the trend.  Since my preference is trend trading, my concentration is the overall move, not so much the swings.

The price chart shows bars that move continuously upward once price moves above the 20 MA (dashed blue line).  That’s clue #1.

Once the trend started, price seldom closed below the 20 MA.  Notice how the volume was higher than the 20 MA of volume.  That’s a good sign this move has support.

The bright blue bar marks the first close below the 20 MA in mid-September (#1).  Not only did price close below that average, it opened below it.

The next bar (#2) was a huge, wide-range bar that opened below the 20 MA, probed below the 50 EMA and then closed at the top of the bar’s range just barely below the 20 MA.

Bar’s #3 and #4 show price opening below the 20 MA again.  Price did move above the line, but never recaptured the prior high.  Then it fell below the 20 MA and eventually, the 50 EMA.  Once price broke the 50 EMA  a serious move to the downside was underway.



Lots of good information from that trend:  price tends to stay above the 20 MA.  When it breaks below the 20 MA it is a warning that price may trade to the 50 EMA.  If price drops below the 50 EMA then it is likely the beginning of a correction.

This is the second up trend and it’s not very smooth.  Volume was above average at the inception of the move.  Again, price closing above the 20 MA looks like a good signal for an entry (dashed blue line).

Point #1 shows a move below the 20 MA, but a quick recovery and then the upward climb begins.

#2 is a price bar that crashes below both of the MA’s.  The next bar recovers the lost ground and really adds to the price.  (Just an aside — those enormous up and down bars can signal exhaustion.  You can see from the follow price bars that price was exhausted and could not exceed the huge bar’s high).

Bars #3 and 4 are the breaks below the 20 MA and then the 50 EMA.  Once the 50 EMA gives way, price corrects dramatically.

New information from this second trend is this:  the stops should not be set too close to the 20 MA.  The evidence is this:  when there is good volume to support the move up, a stop too close to the 20 MA may create a whipsaw.  Price is likely to recover and move up even if it does close below the 20 MA.

So far the clues are:

  • a close above the 20 MA may make a good entry signal
  • heavier than average volume should confirm the price move
  • price breaking below the 20 MA is a warning
  • below the 50 EMA starts a severe downturn

This is the third and last up trend before the long move that began in early 2010.  Again, the signals are very similar: a close below the 20 MA is a warning.  Price  closing below the 50 EMA means “get out of Dodge”

With a better understanding of how APKT trends, my trading rules for trading it would be these:

  • look for heavier than average volume on the signal bar — the price bar that closes above the 20 MA
  • go long above the bar that first closes above the 20 MA
  • sell 1/2 of the position if price closes a few cents, maybe a dime or so, below the 20 MA
  • sell the remainder of the position when price closes below the 50 EMA

This last chart is the current move of APKT from early 2010 to the present.  Now’s the time to see if studying the prior up trends have helped to create trading rules for this stock.

You don’t need a lot of stocks to make money.  Find a few, learn their behaviors, and develop a trading system specifically for them and you can stash a lot of cash!

Why You Should Use A Stock Trading System

Posted December 21st, 2010 by Trading Systems | No Comments

The Gears

When you understand how the market really works you realize the necessity for a good stock trading system.  This came to mind as I perused an article about the market blow up in 2008.  A lot of the big players didn’t believe it and either didn’t have a system or didn’t follow their system.

These were guys who were hailed as the new wizards of smart.

One quote stuck in my mind.  It was how the market is a lot like a poker game.  Here’s an excerpt from the article:

Let’s talk about some of the guys you met and your impressions – Ed Thorp is seen as the father of the quantitative approach, he started out with ‘Beat the Dealer.’ This is a consistent theme, we see these guys playing blackjack, going to Vegas, playing poker. What was your takeaway with Ed Thorp, did you get to meet him?

A: Yeah, I met Thorp many times. He’s totally fascinating, he’s also probably…I don’t know if I respect anybody I’ve ever met on Wall Street more than this guy, just because of his demeanor. When you meet him, you know this is a guy who is completely straight-up, he’s going to tell you what he thinks, he’s a gentleman, he’s also just incredibly brilliant. He’s definitely old-school, he goes back to the days of the Great Depression when everybody had to pinch their pennies, so he’s not a gambler. The thing is, he learned how to beat these games in Las Vegas in a way that he didn’t have to gamble, that was his whole point, that I’m not gambling with my money. For him, it wasn’t about the money. So he was totally fascinating.

And here’s the take away from this article for me:

Not about the money, but rather just demonstrating that a rule-driven, systemic approach to uncertain probabilistic systems can generate alpha. As long as we’re making the right bets, you’re not going to win every deal, but over the course of time, the high probabilistic bets are significantly going to out-perform random bets.

Top Software Reviews “Once A Week Trader”

Posted December 18th, 2010 by Trading Systems | No Comments

Received an email this morning with the link to the review — The Once A Week Trader Review From Top Software Review blog.

Trading Tools

Posted December 14th, 2010 by Trading Systems | No Comments

This trading tool can help you find strong stocks to buy.  It’s on Investors Business Daily’s website.

The scan produces some of the best “young” stocks.

This is the front page of Investors.com.  On the Stock Research Tool window click the drop down box (red arrow) and click Screen Center — Basic.

That opens a second window.  The screen is called Young Guns.  The most important sort, I think,  is the Fundamentals view.  That sorts the list by IBD’s composite rating.

Clicking on the View All button expands the list to the top 20 stocks.  It’s worth a look every once in awhile especially if the stocks in the list are new to you.

Trading Signals: The Price And Volume Relationship

Posted November 29th, 2010 by Trading Systems | No Comments

Running average
Image via Wikipedia

A great deal of ink has been spilled trying to decipher the trading signals derived from the price/volume association.  In reality, volume is most appreciated as a filter.

Volume can validate a move up or a move down.  For example, if price is moving higher on below average volume it’s likely the move is fragile.  When price climbs a good sign is to have plenty of volume behind it.  Volume will push prices higher.

Conversely, when prices start to retreat,  a low volume pattern demonstrates lack of conviction in the downward movement of price.

Two of the most important times to watch volume is when a top or bottom are forming.  There may be a day or two prior to the last high when volume is extraordinarily high.  At that point, it is almost assured that everyone that wanted into the issue now has a position.  Often times volume will start to diminish as price tries to push to higher levels.  That is a sign that the buyers are “all in”.

One reliable sign of a price bottom is unusually high volume.  That action goes by the name of capitulation.  Traders that bought at higher levels have become so sick of their losing position that they dump the stock en masse.  That accounts for the huge volume and the term, capitulation.

One good study to keep on your charts is a running average of volume levels.  That offers a benchmark from which you can decide if volume is above or below its average.  By watching the moving average of volume you may be alerted to an early hint of the strength or weakness of the current price move.

Try This Simple Trading System For Short Trades

Posted November 17th, 2010 by Trading Systems | No Comments

Here’s a quick, low risk, and profitable trading system for short entries –

  • Find a stock trading below its 200 day moving average.  A stock in this predicament is already weak.
  • When it stops declining and starts rising in price, place an order to go short beneath the low of the first up bar.
  • Continue to try and enter short at each bar’s low.
  • Stop trying to enter a short order if the stock breaks to a new high.

Here’s the sequence:

Imagine the blue line as that of a stock that has moved well, but slowed and was eventually stopped at the 200 day moving average.  When price hit the 200 day moving average price fell, as seen in the orange circle.  Now price has picked up steam and is starting to move upward, again — the red line.

The inset shows the bars of the up move.  At the first green bar up, enter an order to short a few cents below that bar’s low.  Continue to place short orders until success, or the top is taken out and price moves beyond the 200 day moving average.

The rationale behind this trade set up is this — you’re looking for the stock to hit the wall again at the 200 day moving average.  If that happens your logical stop would be the first low after the first decline.

I’d sell 1/2 of my position there and hope more weakness would follow!

The Myth Of The Outside Day

Posted November 10th, 2010 by Trading Systems | No Comments

An outside day is a price bar that occurs frequently on a daily chart.  To be a true outside bar it must have a high higher than the previous bar and a low lower than the prior bar.

This is what an outside bar looks like –

There are dozens of outside bars in this Dow Jones Industrial chart.

The common wisdom theory is that an outside bar should have a trader on the look out for an impending trend change. In an uptrend, an outside bar is supposed to signal a down trend is near.  The opposite results would be expected for an outside day occurring during a downtrend.

Really?  I’ve let my system scan the above chart and mark all of the outside bars.  Here’s a look –

It appears that  there were lots of times the uptrend should have been sold if you’re relying on the validity of an outside bar.

I’ve also heard some say that as soon as an outside bar appears look and see if it closes opposite of the overall trend.  If so, price will follow the direction of the bar.  In other words, in and uptrend if an outside bar is made and it closes lower (a red bar), it means that price will trade lower.

The blue arrows show where the market should have been sold given the red outside bar.

The only reliable signal looks like the one marked by the blue arrow in the yellow circle.

Outside and inside bars (price is entirely encapsulated by the prior bar) are fun to spot, but I’ve never found them very useful by themselves.

I much prefer to find trend changes with a trend line and moving average break.

My system would find a possible trend change at least three bars earlier than the last red arrow/outside day on this chart.

I would be concerned about a trend change at the bar marked by the curvaceous blue arrow.  Not only did price fall below the trend line, but it broke and closed below the 20 moving average.

Outside bars, in my opinion, may reference a day of  indecision.  Sometimes there will be an outside bar and then a couple days of sideways trading.

Price patterns are interesting, but a one day price bar does not persuade me.  It pays to be somewhat skeptical when so many see the same thing on a chart.  Often the obvious is obviously wrong.

Good Trading Systems In Bad Times

Posted November 4th, 2010 by Trading Systems | No Comments

Successful trading systems take advantage of conflicting information.  That’s when you’re likely to make the most money, when no one else believes what you believe.

“Buy when there’s blood in the streets.” –  Baron Rothschild

Did your system flash buy signals here?

I was trading full-time during those lows.  Doubt and skepticism was rampant when the market started to rise.

Watch for pull backs.  They’re all over the charts.  On this daily chart there were  plenty of pull backs to trade.  Here’s a bunch over three years.

You could knock the time frame down from daily to hourly, hourly to a 30 minute chart, etc.

Trading the pullbacks can create some wicked profits!

If you don’t have a pullback strategy, I’d encourage you to add one.   Start by adding a pullback system for long trades and keep it simple.

As you build more systems there will be more opportunity for confusion to sneak in to your trading decisions.  Here’s a piece of advice — make a “play sheet” and keep it on your desk.  I’m speaking of the same kind of laminated sheet the NFL coaches have on the side lines.

Create one that has the rules of your systems on it.  It can save your time and keep your from making bad decisions that cost money.
