Trading view with 3 diferentes criteria

Theres an indicator on tradingview (no source code) its about multiple sma and i can create a crosover alert between 2 diferents SMA.( I NEED THE ALERT ONLY OF THIS INDICATOR CAUSE HAS FLAT PERCENT ETC..). So the only thing thah i need is add a crossover ont his 2 diferents sma crossover BUT only if is in certan CCI level ( free source code ont radingview)
