Help on EFS to measure angle of EMA

[earlinarizona]

I wanted to take the current bar value and subtract it from the last bars value. Then that number could then look up in a matching table what to display on the screen. This would show the degrees of the line.

Table example

Difference of 3 would display 3 degrees
Difference of 7 would display 9 degrees
I would fill in the rest.

Display on chart Like this if
{
drawTextRelative(1, 80, "Sell right now @ " + close(), Color.black, Color.red, Text.FRAME | Text.RELATIVETOP | Text.BOLD, null, null, "OS");
} else if {
drawTextRelative(1, 20, "Buy right now @ " + close(), Color.black, Color.green, Text.BUTTON | Text.BOLD, null, null, "OB");
}


and so on. I would have to fill in correct values for EURO as one EFS, Russell as one EFS and Bond as one EFS. Once this is doe it never has to change.
You know woodies rules. Never trade with a 34EMA with less then 15 degrees, and this has kept me out of al lot of chop.

I noticed that the 34EMA attached was done in the wizard and wondering if you can figures out on the wizard if this is possible and if you could do it and I will do the tables of degrees of 0 degrees to 90.
Below is the EFS which was made in the E Signal wizzard that this feature would be added to.

Not sure I understand..

Do you want "actual degrees of slope" or just "the point difference from the past bar to the current bar"???

What would the "lookup" function do....???

I'll help if I can.

EMA degrees progress.

The codeo or wizzzard is almost done. Another person figured out how to do this and I just filled in the value difference and degrees. The only thing that needs to be done is the value to show up in the window like a text box. It would say for example "30 degrees" When the angle is less then 15 degrees all of us stay out. So all should be complete except putting the degrees on the screen . Could you help me on that one since I am a trader and having trouble as a programmer.

[email protected]. If you could send me your e mail or tel # it could speed this along.
Thanks

Formula Wizard on 34 EMA

Hi:
I am playing with Earl's 34 ema Formula in the wizard and my lack of experience is showing.
I am getting a syntax error when I attempt to replace the 34 EMA with a 50 EMA.
What I did:
Go through the efs and change the 34 to 50.
Then, I did a syntax check and I get an error in the formula down below when it refers back to the 34 EMA.
Then, I attempted to go down to this section and manually change the 34EMA to a 50 EMA.
My question:
Why is this not working?
(Does it not like me?)
When I go through the Formula wizard, why can I not not see a reference to this section of code?
I am attaching the efs

Harndog
Open the efs with the Editor and replace vEMA34_of_HLC3 with vEMA50_of_HLC3 in lines 65 and 67
Also, you can't use the Formula Wizard on that formula at this point.

I changed it and reposted, too many things changed for me to tell you exactly what happened
