Slope()...

[funk101]

Thanks for the Slope(). Please explain this. My 2 studies are clearly pointing up for currentbar and previous bar. However, as you can see, my readout is showing a negative number. Why? (see attached)

My code:
slowLine = Slope(CCI(14), 1, 0);
fastLine = Slope(CCI(6), 1, 0);

I tried Slope(CCI(14), CurrentBar-1, 0); But got some really funky output. A very large number. I just want the slope from previous bar to current bar.

BTW, what is your formula for the calc'ing of Slope();?

Forumula was incorrect. Here is what I am changing it to for the next update. Thanks for pointing this out. I had endBar - startBar, which is correct if the parameters passed in were absolute bar numbers which they are not. They reference the number of bars ago.

return (series[endBar] - series[startBar]) / (startBar - endBar);

Ah!

Whew! I thought it was me. Glad I could be of service. Thanks, let me know when the update is available.

Any idea when we'll have the updated slope() method available? I'm unable to edit the indicator because I can't see it.

[NinjaTrader_Ray]

Likely end of this coming week.

[AO76]

Bump any date on the update?

[NinjaTrader_Ray]

I am hoping early this coming week. Just doing some final testing.

[AO76]

Great Thanks.

Ray,

Is this slope() function using math.atan to calculate slope?

[NinjaTrader_Ray]

No it is not.

Slope()

If I just want to buy when the 50 EMA slope was greater than 20 degrees, could I use the Slope() to do that? If so, how?

[NinjaTrader_JoshP]

Yes. Just place the slope function inside an if statement.

[edgeliner]

Can you give me an example?

[NinjaTrader_JoshP]

if ((System.Math.Atan(Slope(EMA(50),CurrentBar-1,CurrentBar))*180/Math.PI) > 20)
     // Do something

Review the discussion here about slope. http://www.ninjatrader-support.com/v...ighlight=slope

It has many examples and many different implementation variants that people like to use.

Note: A condition of 20 degrees in slope is pretty rare. You usually don't even see 10 degrees of slope.

You are the best Josh!
