Happy Friday Bruce,

I know we can’t really backtest in TC2000 but since we can export chart data I’d like to take a stab at a simple algorithm using the available 500 bars of data.

For this one we’re using the daily timeframe exclusively. (I know, right?)

I’d like to plot the following Indicator PCF Formulas on the chart so I can export them:

  • The average close of the last 20 days
  • The average close of the last 20 days starting 3 days ago
  • Today’s close
  • The close 3 days ago
  • The close 3 + 20 days ago

I’d also like to plot the following Condition PCF Formulas on the chart (maybe as rows of green and red dots?) so I can both eyeball the chart to see when the conditions are true and also export their values:

Bullish

  • True if the average close of the last 20 days is greater than the average close of the last 20 days 3 days ago.
  • True if today’s close is less than the close 3 days ago.
  • True if today’s close is greater than the close 3 + 20 days ago.

Bearish

  • True if the average close of the last 20 days is less than the average close of the last 20 days 3 days ago.
  • True if today’s close is greater than the close 3 days ago.
  • True if today’s close is less than the close 3 + 20 days ago.


In other words, given that X = 20 and Y = 3, for buys:

  • The average close of the previous 20 days must be greater than the average close of the last 20 days starting 3 days ago.
  • Today’s closing price is less than the closing price 3 days ago.
  • Today’s close is greater than the close 23 days ago. 

Doable?

These are all pretty straightforward if I am understanding your post correctly.

Bullish:

AVGC20 > AVGC20.3 AND C < C3 AND C > C23

Bearish:

AVGC20 < AVGC20.3 AND C > C3 AND C < C23

Yeah, keeping it simple this time. Actually just wanted to test something I read in a book about money management. Interestingly, over 90% of the book is money management - there's only one chapter on "systems" and you just coded it. I guess the author's point was that it isn't what you trade as much as how you trade it. We'll see. Wish I had more than 500 bars, but it's a start. :)

Thanks, Bruce ... enjoy your weekend!!

Before I forget - do you know what causes the &rsquo: thing? It doesn't show up in preview mode when I'm proofreading. I usually write longer posts in a text editor first, but I'm usually careful about using a plain old text file.

I think it might be caused by a bug in preview mode actually. What is happening is that it is displaying some of the HTML instead of interpreting the HTML (as if PerserveHTML is checked). I don't think it happens if you avoid using preview.

Good morning Bruce!

Okay, apparently one cup of coffee isn't enough...

I created eight Condition PCF Formulas:

  • AVGC20 > AVGC20.3
  • C < C3
  • C > C23
  • AVGC20 < AVGC20.3
  • C > C3
  • C < C23
  • AVGC20 > AVGC20.3 AND C < C3 AND C > C23
  • AVGC20 < AVGC20.3 AND C > C3 AND C < C23

I'd like to plot these as eight rows of dots, but I'm having a brain cramp. What's the technique again?

Maybe try adding using the following formulas as Custom PCF Indicators in the same pane and scale.

8 / ABS(AVGC20 > AVGC20.3)
7 / ABS(C < C3)
6 / ABS(C > C23)
5 / ABS(AVGC20 < AVGC20.3)
4 / ABS(C > C3)
3 / ABS(C < C23)
2 / ABS(AVGC20 > AVGC20.3 AND C < C3 AND C > C23)
1 / ABS(AVGC20 < AVGC20.3 AND C > C3 AND C < C23)

The New button has Condition (PCF) Formulas and Indicator (PCF) Formulas ... how do I create Custom PCF Indicators? 

I should have really made an entire pot of coffee. :)

Thanks, Bruce. Been a while since I did the "Custom" thing; apparently haven't committed it to memory yet. By default I usually go to the "New" button first.

Tr&eacute;s Cool!! I've seen similar screenshots in the forums before - wondered how they did it. I shuffled the order a bit, but this techinique is awesome.

Thanks again!!

I'm really beginning to be annoyed by that ampersand. :)

Bruce, another question...

I separated the individual PCFs in the bottom pane for now. Eventually I'll probably pin them off to the side.

What I ultimately care about are the Bullish and Bearish signals provided by the "compound" PCFs. How do I edit the PCFs to get both the red & green dots on the same row? Trying to save screen real estate...

Make the number at the front the same....

1 / ABS(AVGC20 > AVGC20.3 AND C < C3 AND C > C23)
1 / ABS(AVGC20 < AVGC20.3 AND C > C3 AND C < C23)
