# Forex Signals and Forecast Currency Indicator is based on the well-known Super Trend indicator.
# We added a filter based on the Moving Average to get rid of noise and refine the indicator signals.
# By filtering signals, we were able to improve the accuracy of the indicator's currency trend prediction,
# as well as increase the overall efficiency of the indicator.
