They aid in the charting of curves, rectangles and triangles through which the forecasting of the forex market is done.

- Introduction of bars in the fractions. Earlier, the numerator used to have quotations around it.

Later it was discovered that the Fibonacci numbers and the respective series were not only limited to the arithmetic but it also played a pivotal role in economics, commerce and trading sectors too.
