Stick Maps, from Victor Niederhoffer
Marshall Islanders use stick maps to navigate the currents between the 4 islands which are on straight lines of a square.
Where the currents from the two equidistant islands cross, they find turbulence.
Navigators from other countries memorize the stick maps to guide them when approaching the islands.
Would stick maps be useful for market prices? Perhaps between bonds, stock, gold and currencies.
