Same Formula used multiple times in EFS

[OpaBert]

I have a piece of code / EFS that works fine.
I use it 2 times on a chart first based on High.
Then I edited it to be based on Low.

How do I change the code to combine so that one EFS will do / plot both lines?

setStudyTitle("Berts SELL");
setCursorLabelName("LR-L Curve");

and

setStudyTitle("Berts Buy");
setCursorLabelName("LR-H Curve");

NEW would be combined ...

setStudyTitle("Berts BUYnSELL");
setCursorLabelName("LR-L Curve");
setCursorLabelName("LR-H Curve");

------------------------------------------------------------
Here is the original code.

/************************************************** *****************

var bInitialized = false;


function preMain()
{

setCursorLabelName("LR-L Curve");

// Number of Bars before signal is cancelled
var fp1 = new FunctionParameter( "frLength", FunctionParameter.NUMBER);
fp1.setName( "Length" );
fp1.setLowerLimit(0);
fp1.setDefault(20);

//Line thickness
var fp2 = new FunctionParameter( "LineThickness", FunctionParameter.NUMBER);
fp2.setName( "Line thickness" );
fp2.setLowerLimit( 1 );
fp2.setUpperLimit( 10 );

// Filter on Mean Swing Line
var fp3 = new FunctionParameter("LineColor", FunctionParameter.COLOR);
fp3.setName( "LineColor" );
fp3.setDefault(Color.red);

// end of formula paramaters

}
function main(frLength,LineThickness,LineColor)
{
var len = frLength;
var vPrice = getValue("Low", 0, -len);
var Num1 = 0.0;
var Num2 = 0.0;
var SumBars = len * (len - 1) * 0.5;
var SumSqrBars = (len - 1) * len * (2 * len - 1) / 6;
var SumY = 0.0;
var Sum1 = 0.0;
var Sum2 = 0.0;
var Slope = 0.0;
var Intercept = 0.0;
var i = 0;

//script is initializing
if ( getBarState() == BARSTATE_ALLBARS ) {
return null;
}

//initialize once-only paramaters
if ( bInitialized == false ) {

setDefaultBarFgColor( LineColor, 0 );
setDefaultBarThickness( Math.round( LineThickness ), 0 );

bInitialized = true;
}

for (i = 0; i < len; i++)
{
SumY += vPrice[i];
Sum1 += i * vPrice[i];
}
Sum2 = SumBars * SumY;
Num1 = len * Sum1 - Sum2;
Num2 = SumBars * SumBars - len * SumSqrBars;
if (Num2 != 0) Slope = Num1 / Num2;
Intercept = (SumY - Slope * SumBars) / len;
var LinearRegValue = Intercept + Slope * (len - 1 );
return LinearRegValue;
}

I added a "BERT" button so you don't have to reload to change the parameters.

EFS attached.

FWIW he would not need to reload the efs to change the parameters.
All he would need to do is right click the chart, select Edit Studies and call the study from the dropdown list (or select the chart and then in the main menu click Chart Options->Edit Studies which is the same thing)

Squiggley Lines !

Thanks Avery,

They may be squiggley lines but you would be amazed at how accurate they are to consistently pull money out of the market when used properly.

Now if I only had my Dynamic S/R ... LOL

Thanks.

I had asked about this days ago!!

But, that's still a bunch of clicking.

Re: Squiggley Lines !

Ok, so then explain, in detail, how to use those squiggley lines.

Bert:

Here's a present for you... $BERT_RIBBON

I created this to see if I can understand how your squiggley lines can make me money.

But there is something weird going on with this code.

var vaLRV = ( LinearRegValue, inv(xInterval) ) ;

But, vaLRV is NOT equal LinearRegValue?!??!

Maybe someone can figure it out.

Using Squiggleys!

Duh, How easy can it be ... Attach File

[OpaBert]

Here's the info / what you should know about my "Squiggley Lines Method".

1. I trade the DAX Futures Index.
Every 1 point move is worth 25 Euros so call it 25 bucks.

2. I go for 2 or 2-1/2 point scalps and longer runs when the setup is right.

3. My total cost in and out (Round turn) is about $6.00 per unit.
So even if I exit with only a 1/2 point I still have a profitable trade.

4. I usually trade 1 unit unless the setup is very strong.
Then I might go with 2 or 3 units / contracts.

5. To trade 1 contract you need to have at least 5 to 6 K$ on account.

6. I'm NEVER holding over night.

7. DAX trades from 2 AM to 4 PM EDT and it would be very unusual if you couldn't do at least 2 trades per hour.
Making several 100 dollars gets easy once you get comfortable with the method.

(There are many other advantages to trading this way as well.)

8. You need 3 "Berts" on a chart. 20, 50 & 150 (Green = H, Red = L)

9. You also need an EMA(20) (Blue)

10. I add extra stuff, but it's not necessary.
For example in the AAPL chart in post "Using Squiggleys! - Posted: 07-27-2006 11:25 PM"
I added Avery's "TRO_TREND_LowerMin" to see how much confluence there would be.

11. I Day Trade trade using a 1 minute real time chart.
This method appears to work in any time frame and for any equity.

12. The entry is very simple.
You might even be able to program the buy and sell signals with a background color and audio clip.
(I use the Navy General Quarters announcement having spent 23 years in the service.)

For a BUY:
If prior close was below EMA(20) and now
IF Close is above EMA(20) and
Close is above any TWO Berts Green Lines then go Long.

Experience will give you a feel for the entry price between Close and EMA(20)

13. If you want to stay in / ride the trade a conservative exit would be
a close below the Berts Red Line immediately below the entry.
(with each new bar exit is adjusted)

14. Definately Bail if Close is below EMA(20) and Red line as described in 13 above.
When you are wrong, nothing is 100% in trading, you catch it quickly.
Knowing where my Dynamic S/R Zone is will help reduce wip-saw.

15. Short using the converse approach to EMA(20) and Berts Red Lines.

Feel free to PM me for more info, especially if you trade DAX.

I'd also be interested in working with a knowledgeable EFS programmer to develop an actual trading system
that identifies the trades with visual and audio ques plus test the automatic trading possibility.

Bert.

Bert:

Thanks for sharing.

[OpaBert]

My &quot;Squiggly Lines Method&quot;

Hi Avery,

NO SQUIGGLY LINES on the chart (that would make you happy! )
instead, for a BUY:
Draw a Horizontal Bright Green "Segment" from the "signal bar Close" 10 bars to the right and,
Draw another Horizontal Bright Green "Segment" from the "signal bar "
(Close minus ((Close minus EMA(20)) / 2))) 10 bars to the right.

This would represent the optimal buy zone.

For a Sell:
Draw a Horizontal Red "Segment" from the "signal bar Close" 10 bars to the right and,
Draw another Horizontal Red "Segment" from the "signal bar "
(Close plus ((EMA(20) minus Close) / 2)) 10 bars to the right.

This would represent the optimal sell zone.

And if you really are up for a challenge to impress us,

Make the background in the horizontal Buy Zone a pale green and the background in the horizontal Sell Zone a pale red.

Additionally, you might want to include the "Play Sound" feature when a Buy / Sell is triggered.
I use audio a lot so I don't have to stare at the screen.
That way I can be doing other things and just let the computer call me when a trade is possible.
Reference my attached "HeadsUp" audio file.

PM me if there are any questions. Thanks again.

Sample Buy / Sell Zones

Here's what the Buy / Sell Zones would look like WITH the "Squiggly Lines" on the chart.

Notice I made the 10 Bar Horizontal lines thick for better visability.

[OpaBert]

Buy / Sell Zones WITHOUT Squiggly Lines

Here's what the Buy / Sell Zones would look like WITHOUT the "Squiggly Lines".

Notice also that in all 5 trades identified, at LEAST 2 points were easily attainable. (Often more)

10 points = $250.00 between 12:30 and 14:30.

With audibles included you can snooze and trade!

The reason you would want to keep the "Squiggly Lines" on the chart is to help you stay in or get out of a trade.
Maybe that's where the Slot Machine comes in?

[OpaBert]

Sorry Avery, the code is way beyond me.
