Release Notes

v5 - added exported functions for the first time; will probably store more here, in order for them to be on only one place and to be able to apply them on many places more easily

Release Notes

v6

Added:
func_strong_bullish_alignment_by_bar_index()
returns if at a specific index, the array value on it is above ema1, above ema2, above ema3
Returns: if at a specific index, the array value on it is above ema1, above ema2, above ema3

func_strong_bearish_alignment_by_bar_index()
returns if at a specific index, the array value on it is below ema1, below ema2, below ema3
Returns: if at a specific index, the array value on it is below ema1, below ema2, below ema3

func_turn_series_to_array()

func_get_bull_and_bear_cross_indexes(arr)
returns if source has strong bull/bear alignment compared to its emas and the bull/bear cross index if there is such - so if the emas are 20,45 and 200, if price is above 20 and 45 and these two emas are bullishly crossed, but
they are below 200, the index will be -1
Parameters:
arr: - the array of values (could be close values of candles, could be asset vs market (index) values), which basically contains the source; source is e.g. price close, or index; the emas are of the source

v7

Added:
func_generate_relative_strength_data()

func_cross_of_source_and_200_ema()
creates an array with the source values you pass as a parametr; starts counting from the most recent element (the element now) and continues backwards and checks if the source had
bullishly or bearishly crossed the ema200 parameter that was passed; also writes in the table myTable some values
Returns: bool- if the last index of crossing the source with the ema200 was a bull cross or not
