Scalper Buys/Sell Replica

Here is a very useful addition to the Scalper Buy/Sell. The red arrow above or below shows the trigger bar and after the confirmed Scalper signal disappears.

 

This is a NT screenshot and the code is publicly available.

Luis, you are the best !

I've had all the TTM indicators from traderslabratory except for this one. Funny thing is, I wrote a letter to carter telling him how expensive I thought his indicators were and that under $1000 sounded better. 2 weeks later they were reduced, but it was a week to late, had already found 90% of the indicators "free" here.

You have just completed the series.

Thank you

 

p.s. Anyone bought the Journal from TTM it is worth the money and you can easily go to http://www.johnmote.com/ Excel spreadsheet password crack to expand it and get rid of the huge TTM logo.

Just wanted to give back

Hope someone can help. When I use the scalper buy/sell indicator, ever so often I seem to get an incorrect signal. I have seen this on many different time frames. I'm attaching two images that highlightthe problem. Any help would be much appreciated.

Hello Shawn,

 

as far as I understand this indicator (the original and this replica), I think that everything is OK.

Just that you know, I don't own a license regarding the original and I don't use this replica.

 

OK, but let me try to explain:

In your first example, a red (sell) bar is plotted after some time (pivot bar).

To do this, you need a trigger bar just behind it.

A trigger bar is a bar with no new high behind a potential sell pivot bar. Now we need a close on a following bar lower than the low of the trigger bar without a new high, to mark the potential pivot bar as such.

 

Hopefully this is understandable. Otherwise, try to explain your example two, and we can discuss it here.

 

 

Cheers,

 

Hal

Hi,Could some one please provide the indicator for ninja trader.thanks,Andreas
The Scapler is actually part of the indicator package in the latest NT so currently you don't need to import it. It was originally ported/coded by Gumphrie, but there is no guarantee that NT won't remove it from NT once TTM starts marketing their TTM suite for NT. So here it is the attached and code listed :

// Scalper v0.1 by Gumphrie, inspired by John Carter's TTMScalper
// v0.2 - removed the period parameter as pretty much useless and changed all the high/low calaculations to be one bar ahead
// v0.3 - fixed possible plotting error
// v0.4 - additional check for highest and lowest
// v0.5 - reduced cpu usage & added trigger bar alert arrows

Thanks for your reply Hal. I now have a better understanding of how this indicator works

Hi Luis..Thanks for the indicator..I noticed today using it that it did not pick up a couple of signals on a 60 min chart. By the definition you offered, with a higher low of last two bars, then a lower low, then a break of that bars low..and it didnt paint.. Have you ever noticed it miss some occurances?? Thanks for any feedback.. CG

someone mentioned the other indicators are around here somewhere. Can you please give me an idea of how I would go about finding them?

 

I use NT and there was also a post showing red signal arrows occurring right after the white signal bar. Does anyone know where to download the code for this to NT?

 

Thanks,

Gecko

I downloaded this to my esignal indicators and it says error -line 1: syntaxerror: illegal charactor. any advice? thanks

It is unlikely that Esignal can run Tradestation EL code. The following Esignal code by rebkwez may help:

 

Here is the esignal code that I wrote. I'm not completely familiar with TS code, so I did my best in trying to do the conversion. Also used the TTM videos as guidance, but the explanation there is very unlcear.

 

Esignal doesn't have the PaintBar concept that TS does, so right now a box with a "B" or "S" appears above/below the candlestick that generates the signal. The distance above/below where this box appears is fixed in the code. It probably should be made into a parameter so it can be changed for stocks, fx or futures. For the next version...

 

If anyone makes any changes to improve on this code, please post it to the list. Thanks.
