Great Idea for EFS!!!

LR Bands

They tend to show wave 5's by the way price moves under or over. Best to use Bollinger band. On true wave 5's the BB band and the LR Band will "link" up for a few bars then price will "peel" away. Best used on 15 minute or 60 min. Only get 2 or so plays a week on 15 min chart but trade tends to move quickly and very high success rate. The charts are cluttered too with the lines on it but you get use to it.

Play around with length. I use 13 period for linking with BB band and 65 period for trend.

I don't have the lsma.efs and I don't know where to find it?

Here is a 21 lsma I found on Yahoo

We have one in our library. Please see http://forum.esignalcentral.com/show...&threadid=1692

LSMA

Yes this lsma.efs was developed to go with the woodie cci. What I need is a 3 line lsma to create channel lsma.

I have no use for the lsma.efs and it does not have anything to do with my efs

Thanks anyway,

Hi Realm,

Can you modify the existing one with adding the two extra lines for me??

John

[realm1]

John I do not use the lsma.efs To be honest I have no idea or interest in what it does. It has nothing to do with my strategy that I am aware of. If it does, it would just be another indicator to clog my screen.

I am just using the Candlewaistsweet.efs.

Applying 2 ignore rules for false buy/sell signals.

#1 Ignore signals in consolidation areas

#2 And be very sceptical (if not ignoring) of false buy/sell signals at major pivots ( maybe minor too)

Remember you need to incorporate volume and other indicators too.

HI,

That's ok. If you feel like doing it then great if not then I understand. We all have different styles. I can not make money unless I sell the tops and buy the bottoms and this regression tool has unique properties that are apparent only at extremes.

Thanks again,

John

BTW, I hope everyone's football team wins this weekend.

[realm1]

I am not the one to ask to do the actual code. I only have the ideas. Honest I am a below average coder so I could'nt help you ayways. I am just learning the basics at this point. i did not even build my efs. idea I had the one below do it.

Acutally I was trying to find a autoregression tool I had before I re-intslled my OS system and lost because of an issue I won't mention. Someone built this efs, although I cannot find it. DEPRESSING to be truthfull it worked great.
I know its on here somewhere just have no idea where or what the name is. I had to give upbecause I could'nt get anyone to find it. If you search for posts under my name you will find the post I was talking about it in. TITLE should be (Auto regrtession/trend tool)

I would do it if I could!

Sorry,

YEAH GO FOOTBALL!!!!

What was doing the Efs you looking for?

John,

I understand the LSMA pretty well that I may be able to help. How would the 3 lines be calculated? In other words, the upper and lower bands of the channel would be offset from the LSMA by what factor?

[realm1]

Thanks for stepping in Jayf. I'm just a thinker not a programmer. lol

Have a great weekend!

John,

Thanks for your PM. Here's my interpretation the formula you mentioned.

Jay,

I swear man, thanks so much. I understand why esignal is harder than ts. It is simply because TS's easy language is an interpetive (sp) language and Java Script is a open, stand alone platform.

I can not wait to get rid of TS and just use ES.

Thanks

John

PS, Can you write a volume indicator that only picks up trades with more than n shares or contracts?? I am interested in a volume indicator for ES emini that only picks up trades with more then 100 contracts.
