magarto indicator

You also need to add a MA30 to the chart and set a timeframe of W on FOREX and others and H4 or D for BTCUSD .
Buy: when MA30 changes from downtrend to uptrend, price is over MA30 and magarto indicator shows a crossover in the top.
Sell: opposite scenario

Update 1: Sorry, for LTCUSD it didn't work. I used the wrong chart when I published it so check it in BTCUSD .
