Does Anyone have the TTM Scalper Code for Esignal???

Recommended Posts

Welcome to the forum. This indicator looks better than it actually is. :)

It actually plots the scalper bar usually about 3 bars later, retrospectively. That makes it hard to use in any strategy (and hard to program if your platform doesn't support such plotting).

 

Here is the C# code from NT. Perhaps you can adapt it for Esignal.

http://www.ninjatrader-support.com/vb/showthread.php?t=2966&page=4&highlight=scalper

// 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

I fully agree with carcanaques. TTM's indicators are way overpriced for something so simple. I can't believe that the scalper would provide any edge at all. It required 3 bars before showing anything and during a consolidation that means getting chopped up. TRO posted his versions of the TTM indicators, wouldn't know where they have gone though.

Here's TheRumpledOne's opinion btw.
