Allert with 2 indicator

[[Deleted]]

i need an alert that could tell me when to enter a trade when these 2 conditions are met: stochastic below level 30 and price below the daily pivot. These 2 conditions must be met at the same time
i think about this solution it should be right?

static datetime   LastClosedBar =D'1980.01.1';


StocCurrent=istocastic(NULL,NULL,12,26,9,PRICE_CLOSE,MODE_MAIN,0);
MaCurrent=iMA(NULL,0,MATrendPeriod,0,MODE_EMA,PRICE_CLOSE,0);
or custom indicator like pivot daily


IF ( StocCurrent <= 30 && Bid <=MaCurrent && LastClosedBar != Time[0])
{
      LastClosedbar = Time[0];
 Alert("sAC (", Symbol(), ", ", Period(), ")  -  BUY!!!"); 
} 

is better to do an EA, or script or something other to do that??

but the usual allert work a lot of time is possible to work just one time??
