 Library "FibRatios"
Library with calculation logic for fib retracement, extension and ratios

retracement(a, b, ratio, logScale, precision)
Calculates the retracement for points a, b with given ratio and scale
Parameters:
a: Starting point a
b: Second point b
ratio: Ratio for which we need to calculate retracement c
logScale: Flag to get calculations in log scale. Default is false
precision: rounding precision. If set to netagive number, round_to_mintick is applied. Default is -1
Returns: retracement point c for points a,b with given ratio and scale

retracementRatio(a, b, c, logScale, precision)
Calculates the retracement ratio for points a, b, c with given scale
Parameters:
a: Starting point a
b: Second point b
c: Retracement point. c should be placed between a and b
logScale: Flag to get calculations in log scale. Default is false
precision: rounding precision. If set to netagive number, round_to_mintick is applied. Default is 3
Returns: retracement ratio for points a,b,c on given scale

extension(a, b, c, ratio, logScale, precision)
Calculates the extensions for points a, b, c with given ratio and scale
Parameters:
a: Starting point a
b: Second point b
c: Retracement point. c should be placed between a and b
ratio: Ratio for which we need to calculate extension d
logScale: Flag to get calculations in log scale. Default is false
precision: rounding precision. If set to netagive number, round_to_mintick is applied. Default is -1
Returns: extensoin point d for points a,b,c with given ratio and scale

extensionRatio(a, b, c, d, logScale, precision)
Calculates the extension ratio for points a, b, c, d with given scale
Parameters:
a: Starting point a
b: Second point b
c: Retracement point. c should be placed between a and b
d: Extension point. d should be placed beyond a, c. But, can be with b,c or beyond b
logScale: Flag to get calculations in log scale. Default is false
precision: rounding precision. If set to netagive number, round_to_mintick is applied. Default is 3
Returns: extension ratio for points a,b,c,d on given scale
