Determine Slope End or Start

[januson 10]

Please take a look at my screenshot, is there any built-in EasyLanguage or custom developed function packages that can tell me the slope and/ or if we are standing at point A or point B?

 

Somehow I need to determine if it's a positive or negative slope within the blue area... could we do something with a triangle?

Not exactly clear what you’re looking for –

 

At Point A or at Point B

 

Inputs: Price(close),MALength(9), SlopeLength(3);  
Var: MA(0),SlopeMA(0) ;  

MA = average(price,MALength); 

slopeMa = LinearRegSlope(MA, SlopeLength); 

plot1(slopeMA,"slope");

 

 

 

 

 

Between Point A and Point B here’s (possibly bogus :missy:) pseudo code for what should be within tolerance for most applications

 

if swinglowbar (…yourMovingAverage… ) then begin
  upCount  = rightStrength // if true start upCount
  dnCount = 0;
end; //  if swinglowbar (…yourMovingAverage … )

if swinghighbar (…yourMovingAverage … ) then begin
  upCount  = 0;
  dnCount = rightStrength // if true start a dnCount 
end; //  if swinghighbar (…yourMovingAverage … )

if upCount > 0 then begin
 upCount = upCount + 1;
 count = upCount;

end else begin
dnCount = dnCount + 1
count = dnCount;

end; // if upCount > 0

slopeMa = LinearRegSlope(yourMovingAverage, count);

 

... and don't update intra-bar...

... you can also do similar things with linearRegAngle function

just from visually looking at it isnt the blue area telling you that slope is positive and when its changing to red, close to slope of 0...

zdo-> I'll try working with those functions, thank you.

 

stanlyd-> hmm, so you're suggesting to keep a record of those 0-slopes? And then make a look-up? Could you explain it a bit more detailed?

[januson 10]

zdo-> Please take a look at the attached screenshot! Is this a correct assumption?

[januson 10]

If you could help me here also, I would be a happy camper

 

Screenshot attached

 

Indicator: JK_LinearRegressionAngleDouble

Value1 = jtHMA(Close, 21);

value2 =  LinearRegAngle(value1,1);


value3 = LinearRegSlope(value2,2);

Plot1(Value3, "LRADouble");
plot2(0, "zero");

i thought you just wanted to know if slope was positive or negative ? You can see tha tjust from looking at the MA. However I guess what your looking for it the exact slope degree at a given point?

Sorry to ask...

What do you mean be see? Is it "see"/ "confirm with" as with my eyes?

[stanlyd 10]

yeah , I refer to see as "confirm with eyes"

u can clearly see when slope is positive and or negative

Yes okay.. I understand, but I need to program it into an indicator/ strategy

In my first post I described two types of measure.

The first - the angle / slope at a given point using a fixed look back

The second - the angle or slope starting from a pivot (of some MA in this case) to its current print.

It looks like JK_LinearRegressionAngleDouble indicator is using the first type of angle with the fixed look back of 1 for the angle (and 2 for the slope ?? the code looks like it's going 'redundant' why doesn't it just return slope with a length of two??) Not getting enough resolution on the image to give you any feedback on that...

 

...and I'm out here still trying to figure out which type of measure you are looking for...

Hi zdo

Thank you for your patience, I've created a screenshot, take a look.

 

As you can see there is a big difference between entering when the slope is negative or postive. And that's exactly what I want to analyze for timing entry and exit.

 

The double regression is a LinearRegressionAngleFC applied

 

Value1 = jtHMA(Close, 21);


value2 =  LinearRegAngleFC(value1,4);

value3 = LinearRegAngleFC(value2, 6);

Plot1(value3 , "LRAFC");
plot2(0, "zero");

 

This is only prototyping

 

What I wanted to create was an indicator telling me if we are in the beginning of an uptrend or in the end. I was able to get the double regression to work, I think it's the PowerLanguageEditor that sometimes gets buggy!

 

What do you think about it?
