Nice one and good jobbut do u have any idea for trading with this nice ind.?:)CJA

[Giuliano]

but what's means this? when the arrow do appears?

What do the arrows mean,which is to buy and which is to sell...

2 Questions: 1st: Is it Corrective indicator or not? Seems very good BUY / SELL Signals at 4 Hours Time Frame and Upper than, But if arrows not be currective.
2nd: Are arrows genesis after candlesticks Finishing or can be change during chandle generation from buy to sell (or sell to buy) ?

Dear ruffneck 75:
I think Yellow arrow (From bottom to top) means BUY & Red arrow (From top to bottom) means SELL. It seems very good signals at H4 and Upper time frames but if not be currective.
did u test it in different time frames for know currection specification of this inidicator?

The problem with Fractal indicators is usually you have to wait for the length of the fractal after its occurrence to actually find out it was a fractal. It appears this is the case for this indicator.

Do the arrows plot on the current price bar or six ( default ) periods after the occurrence of the high?

This indicator looks nice for average traders for a start.

Thanks

WOULD SOMEBODY PLEASE HELP ME. I DOWNLOADED IFRACTALsEX.MQ4, BUT IT DOES NOT COME UP ON CHART. iNDICATOR WINDOWS SAYS ITS THERE BUT NOTHING SHOWS. I TRIED "COMPLING", STILL DOESNT WORK. WHAT SHOULD I DO ?????????????????

I did a little improved and more flexibile version of this nice indicator.

Improvements:

1. changed colors,

2. changed arrows (exactly like Williams fractals)

3. custom left period and custom right period of the fractal,

4. custom number of pips

5. custom error in pips (more flexible comparing between current bar and left/right bars)
