*Part A written formula

*Part B Result of test  - show true even though many parts of the PCF are false.

However if certain parts are deleted the result is true.

Can you please review my formula and tell me what I am doing wrong?

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

            (AVGH5.1 + AVGL5.1) / 2 > (AVGH5.2 + AVGL5.2) / 2

AND (AVGH9.1 +  AVGL9.1) / 2 > (AVGH9.2 + AVGL9.2) / 2

AND H1 > H2

AND H2 > H3

AND L1 > L2

AND L2 > L3

AND C1 > (H2 + L2) / 2

AND C2 > (H3 + L3) / 2

AND C3 > (H4 + L4) / 2

AND C1 > (MAXH3.1 + MINL3.1) / 2

AND (AVGH45.1 + AVGL45.1) / 2 > (AVGH45.2 + AVGL45.2) / 2

AND C 1> (AVGH45.1 + AVGL45.1) / 2

AND L < L1

--------------------------------------------------------------------

(0.79 + 0.73) / 2.00 > (0.82 + 0.76) / 2.00 AND (0.79 + 0.73) / 2.00 > (0.78 + 0.72) / 2.00 AND 0.72 > 0.77 AND 0.77 > 0.80 AND 0.67 > 0.75 AND 0.75 > 0.77 AND 0.69 > (0.77 + 0.75) / 2.00 AND 0.75 > (0.80 + 0.77) / 2.00 AND 0.79 > (0.80 + 0.74) / 2.00 AND 0.69 > (0.80 + 0.67) / 2.00 AND (0.87 + 0.83) / 2.00 > (0.88 + 0.83) / 2.00 AND 0.65 1.00 > (0.87 + 0.83) / 2.00 AND 0.65 < 0.67

Result is true

Getting rid of the extra spaces and line breaks seems to resolve the issue:

(AVGH5.1 + AVGL5.1) / 2 > (AVGH5.2 + AVGL5.2) / 2 AND (AVGH9.1 + AVGL9.1) / 2 > (AVGH9.2 + AVGL9.2) / 2 AND H1 > H2 AND H2 > H3 AND L1 > L2 AND L2 > L3 AND C1 > (H2 + L2) / 2 AND C2 > (H3 + L3) / 2 AND C3 > (H4 + L4) / 2 AND C1 > (MAXH3.1 + MINL3.1) / 2 AND (AVGH45.1 + AVGL45.1) / 2 > (AVGH45.2 + AVGL45.2) / 2 AND C1 > (AVGH45.1 + AVGL45.1) / 2 AND L < L1

I am not sure what you mean about extra spaces and line breaks. I do not have any extra space or line breaks.

Look at the format of your formula as given in your post.

Look at the format of your formula as given in my post.

They are different. Your version has both line breaks between the formula components and extra spaces that mine does not.

When I copy and paste your version of the formula it doesn't work.

Bruce.

Re above code. I got a perfect result using your code. My code is above. I still do not see the difference. Using the code above - please show me the "extra spaces" and "line breaks:.

Will you do that for me so that I willl understand. For illustration purpose only, can you put the  special character * after extra spaces and the special character + after each line break.

I will appreciate this as I do not trust myself anymore.  

Thanks

george

Sad state of a parser that can't deal appropriately with whitespace! 

This ia a parser bug! Avoidable yes, but still a bug.

Don't expect it to be fixed.

The PCF language is an ancient and primitive scripting language that deserves to be replaced with the cababilites provided by StockFinder's realcode.

PCF shortcommings...

No If then else

No commenting capability

No local variables

No parameter passing

No function calls

One can hope for realcode

Maybe so but TC has never been known to be a programmers paradise. Where it shines is in scans and sorts and with great speed. Almost any system has its idiosyncrasies in some form or fashion. Contrary to popular belief, fancy code does not make a trader more successful. Most successful traders use few if any indicators. Instead of hoping for realcode you should learn how to read price action.Use the strength of TC for narrowing down a list to a more manageable size and use the old eyeball method for your entries and exits.

A good book to learn price action would be -Reading Price Charts Bar By Bar- written by Al Brooks.

Excellent post Booker. I have that book and studied it religiously. Trading price action has improved my trading tremendously.

georgecdemas,
Nothing is obviously wrong about the formula in your Thursday, May 03, 2012 6:53:19 PM ET post. It doesn't have any glaring syntax issues, extra spaces or lines. It also seems to test correctly and nothing has jumped out at me about the symbols returning true or false which would seem to be incorrect.

This formula is not the same formula which was posted in your original Wednesday, May 02, 2012 7:27:08 PM ET post however. I have replaced the extra spaces in the formula from that post with * and placed a + at each extra line break:

************(AVGH5.1 + AVGL5.1) / 2 > (AVGH5.2 + AVGL5.2) / 2+
+
AND (AVGH9.1 +  AVGL9.1) / 2 > (AVGH9.2 + AVGL9.2) / 2+
+
 +
+
AND H1 > H2+
+
AND H2 > H3+
+
 +
+
AND L1 > L2+
+
AND L2 > L3+
+
 +
+
AND C1 > (H2 + L2) / 2+
+
AND C2 > (H3 + L3) / 2+
+
AND C3 > (H4 + L4) / 2+
+
 +
+
AND C1 > (MAXH3.1 + MINL3.1) / 2+
+
 +
+
AND (AVGH45.1 + AVGL45.1) / 2 > (AVGH45.2 + AVGL45.2) / 2+
+
 +
+
AND C*1> (AVGH45.1 + AVGL45.1) / 2+
+
 +
+
AND L < L1

Thank you Bruce for your reply.

I think there is nothing else that can be said. However, I want to correct something that escalated as we went along. It has to do with the "original formula" which was posted. NOTE: That was an edited formula- put together in an attempt to simplify the viewing of the code.

This was the original formula:

(AVGH5.1 + AVGL5.1) / 2 > (AVGH5.2 + AVGL5.2) / 2 AND (AVGH9.1 + AVGL9.1) / 2 > (AVGH9.2 + AVGL9.2) / 2 AND H1 > H2 AND H2 > H3 AND L1 > L2 AND L2 > L3 AND C1 > (H2 + L2) / 2 AND C2 > (H3 + L3) / 2 AND C3 > (H4 + L4) / 2 AND C1 > (MAXH3.1 + MINL3.1) / 2 AND (AVGH45.1 + AVGL45.1) / 2 > (AVGH45.2 + AVGL45.2) / 2 AND C 1 > (AVGH45.1 + AVGL45.1) / 2 AND L < L1

I wanted you to see this - as I feel I have misguided you.

P.S. I am still in the dark.

Thanks for your help!

There is one extra space in that formula that I can see:

(AVGH5.1 + AVGL5.1) / 2 > (AVGH5.2 + AVGL5.2) / 2 AND (AVGH9.1 + AVGL9.1) / 2 > (AVGH9.2 + AVGL9.2) / 2 AND H1 > H2 AND H2 > H3 AND L1 > L2 AND L2 > L3 AND C1 > (H2 + L2) / 2 AND C2 > (H3 + L3) / 2 AND C3 > (H4 + L4) / 2 AND C1 > (MAXH3.1 + MINL3.1) / 2 AND (AVGH45.1 + AVGL45.1) / 2 > (AVGH45.2 + AVGL45.2) / 2 AND C*1 > (AVGH45.1 + AVGL45.1) / 2 AND L < L1

Thank you Bruce,

I believe that could be the problem.

I am highly appreciative of your effort.

George

You're welcome.
