I like the indicator .... but be careful .... buy on the signal ..... but do not wait for the reverse to sell or drawdowns can be HUGE! You need another indicator for exits. EUR/JPY pair works well with this system. IMO
Here is the link to get the free indicator:

There is another indicator [not free] called tfx Reversal ..... these are the exact same indicators. I prefer the free indicator as it is in MT4 file format ..... not in an exe file .... as is ...... tfx Reversal. IMO
