This indicator is really simple. It’s there to visualize important psychological levels, also referred to as Double-Zeros. Most markets tend to behave strangely at psychological price levels like for example Gold at 1000$ or EURUSD at 1,4000. The indicator does only show the nearest psycholgical level of the current price (=if you scroll to the left, there’s always just a single line). EDIT: improved version1: does also show past levels now.
There’s just one parameter:
extern int relDigitPos=2; // position of the relevant digit.
It’s tested, but not excessively. Use at your own risk. Feel free to modify or do whatever with it.
Sometimes the best strategies are also the most simple ones…
