The next indicator draws Fibonacci supports and resistances (9 lines based on next percentages 0%, 100%, 50%, 23.6%, 38.2%, 61.8%, 76.4%) based on predetermined number of bars.
It has the next input:
- periods: Number of periods to calculate Fibonacci levels.
The supports and resistances can be modified in terms of colour, width, style.
Note: The indicator repaints past data when changing timeframe, pair or updating so the only important data is present data that means it makes no sense to backtest how price reacted to the levels.
