Belkhayate’s Center Of Gravity

Nikolay.Gekht · Mon Apr 19, 2010 8:26 pm

The indicator can be used to detect the direction of the trade. Looks, for example the following trade system for details.

Download the indicator:

BELCOG.lua

Hi,

Thanks so much for this indicator, it works really well, my only query is how come it doesn’t load for the entire length of a chart..it seems to only show for a short time length..is it suppose to be that way?

Thanks

Re: Belkhayate’s Center Of Gravity

Nikolay.Gekht · Mon May 03, 2010 7:57 am

Yes. The indicator is drawn for the last N (where N is the first parameter of the indicator) bars only. Moreover, the indicator completely redraws all last N bars when a new bar appears.

Bigger time frame version

Nikolay.Gekht · Wed May 05, 2010 2:37 pm

The bigger time frame version of the indicator:

BF_BELCOG.lua

(the BELCOG.lua must be also installed!)

any possibility of getting a version of this indicator that doesn’t repaint on every new bar?

Re: Belkhayate’s Center Of Gravity

Nikolay.Gekht · Tue Jul 13, 2010 10:02 pm

No, because such class of the indicator (the same is, for example for any approximation indicators or to the wave analysis) always does it. It is specific of the method.

Hello. I search the indicator “Belkhayate Timer” (and not Belkhayate Timing) with Marketscope 2.0 from FXCM ! Can you help me ? Thanks.

Can you provide me code for this indicator or a web reference.

This indicator seems to work quite well. I tried to make a signal but my knowledge is not enough for this task. Here is the code which does not work correctly. It generates signals but not in the right places. Signals must be generated when price touches L3 (L4) or L6 (L7).

Dear Nikolay, maybe you can help?

Code: Select all `– Indicator profile initialization routine – Defines indicator profile properties and indicator parameters function Init() strategy:name(“Gravity signal”); strategy:description(“Signals when Price hits Gravity Edges”);

virgilio · Tue Feb 28, 2012 5:49 pm

Hello developer(s), this is truly a nice treat. There is also another indicator that should be used with this Center of Gravity. It is a timing indicator that reinforces the Center of Gravity’s entry and exit points. It can be viewed at the bottom of page 2 in the attached pdf document (Hot to use Belkhayate). The indicator is is called Belkhayate Timing. Is this something you would you be able to replicate and offer in conjunction with the Center of Gravity? If so, then we have a formidable tool to use. Thank you!

Karlo_Karlo · Thu Mar 01, 2012 6:56 am

Thank you gentlemen, but it looks no different than it was before. There is the MBFX Timing Indicator subject also; MT4 version gives a color line while the lua version gives something very different, which I do not understand how to use. I understand that it’s a subject of intellectual property but it very much looks like that the MT4 Timing Indicator is a colorized version of some common indicator. I tried to look for but did not succeed. What do you think about it?

Re: Belkhayate’s Center Of Gravity

Hug Coder · Fri Mar 02, 2012 7:27 am

Karlo_Karlo: You have to define what you want exactly otherwise it’s not so easy.

If you are requesting another indicator please make a proper request in the request forum, with enough information to make something out of it, e.g. a link or code (and picture+description) of the MT4 version.

Re: Belkhayate’s Center Of Gravity

Karlo_Karlo · Sat Mar 03, 2012 8:49 am

Thank you Hug Coder, Below is the “MBFX Timing.ex4” file, which is the additional indicator for MBFX system. But It is for the MT4 and we do not have a lua version. As it is said in the beginning of this thread that this system is an intellectual property of Mr.Belkhayate and it is not allowed to make a lua version of his indicator without his permission. But I think that this indicator is not a very sophisticated one. I tried to compare it with other common indicators in the MT4 but I could not find anything similar yet. In my recent post I was simply asking your opinion about this indicators resemblance with others.

Re: Belkhayate’s Center Of Gravity

trendwatch · Sun Mar 04, 2012 7:50 am

I’ve read several statements of mr. Belkhayate wherein he states he is in no way related to MBFX. So the MBFX inidcators are not the same as those mr. Belkhayate uses in his system. Just thought you might like know this before you started using these indicators.

Re: Belkhayate’s Center Of Gravity

Hug Coder · Tue Mar 06, 2012 5:15 am

Karlo_Karlo: As I said, if you want another indicator, you shouldn’t post requests in this thread. If what you are looking for is a different version of the Belkhayate’s Timing Indicator (viewtopic.php?f=17&t=715) then post there, otherwise post a new request thread for what you want, with proper descriptions etc.

The file you posted seems to be a compiled file which has no clear text/code so it’s of no use.

Re: Belkhayate’s Center Of Gravity

elliotwave5 · Thu May 31, 2012 8:33 pm

a) Can the Belkhayate indicators (BF long term reg and timing indicators) be used publicly? I believe reading that they are proprietary to him exclusively or are they public? b) currently reviewing an H4 chart and the GBP/USD is way outside the L7 band. am i correct in that this indicates that one should take a long position? how many pips to risk on the stop and what would his limit be on profit taking? any comments or suggestions would be greatly appreciated

Can you create a customizable strategy for this indicator please ? (marketscope 2)

Audible alert when candles collide with L1 or L2 or L4 or L5, L6, L7

Is it possible to define the start and end points for this indicator? Instead of N bars from the present bar to the past, can we define, for instance, Oct 12, 1AM to Oct 14, 9AM for 8H bars? This way we can track the arc for specific waves of a currency.

Thanks,

Hi,

Here me version of Belkhayate’s Center Of Gravity. This version shows the standard “dynamic” BelCoG with default parameters. You can also show the “static” history of this indicator and the slope/direction history of the central line. At least, you can suppress levels if you want.
