I think a little explanation of the parameters is warranted. The system is optimized for Trading on M15. Don't try forcing lower or higher timeframes onto it, it might not work optimally.... Xard's semafors are an outstanding stand alone system. However, I felt that it does not incorporate timeframes higher than 1 hour in a significant way. At the same time the boxes forming again and again as the markets keep making new highs or lows caused uncertainty whether a position could be entered or not.... So I included RSI 3 and 9 in MTF mode from H4. The 4H crosses of the two RSI is itself a very strong trade signal. The concept comes from Cristina Ciurea (Scientific Forex) which is based on 5 and 14 RSI crossover trade signal on 4H. For faster signals on lower timeframe I reduced it to 3 and 9. For inclusion of daily timeframe to have a clearer view of the bigger picture, I included Daily CCI in MTF mode with setting of 5. CCI usually has settings above 14. But for our purpose to detect change in market sentiment on M15 a lower number works really well... So 5 seemed optimal after quite a few trials...... The below screenshot shows recent price action on gold with the indicators....

As a next step, since I know nothing about coding, someone can combine both the indicators into one and unify it in a more coherent way.
