Fibo Time indicators

Hi,

I am looking for a fibo time indicator that goes beyond the standard indicator in MT4. I want it to project time goals from say the last 10 price swings and alert me when there is a confluence of fibo targets at a specific time. I have heard this indicator described as a Fibo Time Histogram.

I am not sure if such an indicator exists for metatrader and will write it myself if I am not successful finding something. I am interested in any indicators relating to fibo time projections however even if they dont perfectly match my description, if you know of any please let me know?

Thanks

James
