The scope of this script is to measure momentum and strenght of EURO and DOLLAR using their indexes. Forza (line) above 0 means EURO is stonger than DOLLAR Momento (histogram) above 0 means EURO has a positive momentum against DOLLAR The added value to see MACD and RSI directly on EURUSD chart is that indexes consider also other pairs so their RSI and MACD has a larger view on forex markets. Script has also an option for multi timeframes. I think that could be used as filters for LONG or SHORT positions in lower time frames.
