I think " if ( alertTag!=Time[0]) " means if not same send mail and alert

but I do not understand " alertTag = Time[0]; " meaning at all .

alet and send mail is finish.why need this code????

if ( (fasterMAnow > slowerMAnow) && (fasterMAprevious <
slowerMAprevious) && (fasterMAafter > slowerMAafter)) {
CrossUp[i] = Low[i] - Range*0.5;
if ( alertTag!=Time[0]) ←
{
PlaySound(SoundWAV);// buy wav
Alert(Symbol()," M", Period(), " MA cross BUY");
SendMail(Period()+" hit MA long ", Bid +"long");
}
alertTag = Time[0]; ← what mean???

}

The logic here prevents multiple alerts during the time period of the current bar.

When a new bar comes, a new alert is possible.

addition

now my EA like this

if(FastMA2 <= SlowMA2 && FastMA1 > SlowMA1)
{
ClosePositions();
OrderSend(Symbol(),OP_BUY,Lots,Ask,Slippage,Ask-SLpips*Point,Ask+(45*Point),"", MAGIC, 0,Blue);
return(0);


i want to change like this

1. 15minutus timeflame happen buy sign

2. if then 5minutes timeflame MA cross buy sign already ,too
ClosePosition. and get new position

if then 5minutes timeflame MA change sell sign already
wait 5minutes timeflame change buy sign ,
then ClosePosition. and get new position


Please tell me how to write this program.
