Thanks for the afl. I wanted to know does the indicator looks into the future.

2. niklravi

hi
it looks better than killer MACD. BUT explorations and scan ismissing. can some one add this?

ravi
qatar

3. nunun

The indicator looks into the future..be careful

4. Rakesh Kumar

Buy Sell signals are dynamic, so trader carefully.

5. godisbogus

This indicator is of no use to anybody. Because the signals looks into the future. Buy and Sell arrows appear and disappear once the highs and lows are crossed. Just i wasted my precious time going through this.

6. parfumeur

This is the exactly the same as:

with: _SECTION_END(); on Line 204

7. panjasandeep

Useless. The chart is forward looking and repainting.
