Belkhayate's Center Of Gravity

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

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

[Nikolay.Gekht]

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.

Ahhhh yes. A 'selling into strength' system... just what my bank account needs!

[jefftrader]

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

[Nikolay.Gekht]

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.

[Apprentice]

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?
