MACD Zero Line Alert - Cannot find it on FF

Hi,

I am looking for a MACD indicator on 5,13,1 settings and when it crosses the zero line each time (from positive to negative and vice versa), it pops up an arrow and alerts and possibly emails me.

I have had a look around for this type of indicator and cannot find this.

Thanks in advance,
Guess

I have found an EA, if this helps, though really require an indicator.

int start()
{
//---- Remember the indicator's values for further analysis
//---- Note that we use the 1st and the 2nd bar. This allows a 1-bar delay
//---- (i.e., the signal will appear later), but protects against repeated opening and closing
//---- of positions within a bar
double MACD_1 = iMACD( Symbol(), 0, 12, 26, 9, PRICE_CLOSE, MODE_MAIN, 1 );
double MACD_2 = iMACD( Symbol(), 0, 12, 26, 9, PRICE_CLOSE, MODE_MAIN, 2 );

int _GetLastError = 0, _OrdersTotal = OrdersTotal();
//---- search in all open positions
for ( int z = _OrdersTotal - 1; z >= 0; z -- )
{
//---- if an error occurs at selecting of a position, go to the next one
if ( !OrderSelect( z, SELECT_BY_POS ) )
{
_GetLastError = GetLastError();
Print( "OrderSelect( ", z, ", SELECT_BY_POS ) - Error #", _GetLastError );
continue;
}

//---- if the position was opened not for the current symbol, skip it
if ( OrderSymbol() != Symbol() ) continue;

//---- if the BUY position has been opened,
if ( OrderType() == OP_BUY )
{
//---- if the MACD has met the zero line top-down,
if ( NormalizeDouble( MACD_1, Digits + 1 ) < 0.0 &&
NormalizeDouble( MACD_2, Digits + 1 ) >= 0.0 )
{
//---- close the position
if ( !OrderClose( OrderTicket(), OrderLots(), Bid, 5, Green ) )
{
_GetLastError = GetLastError();
Alert( "Error OrderClose # ", _GetLastError );
return(-1);
}
}
//---- if the alert has not been changed, exit: it is too early for opening a new position
else return(0);
}
//---- if the SELL position has been opened,
if ( OrderType() == OP_SELL )
{
//---- if the MACD has met the zero line bottom-up,
if ( NormalizeDouble( MACD_1, Digits + 1 ) > 0.0 &&
NormalizeDouble( MACD_2, Digits + 1 ) <= 0.0 )
{
//---- close the position
if ( !OrderClose( OrderTicket(), OrderLots(), Ask, 5, Red ) )
{
_GetLastError = GetLastError();
Alert( "Error OrderClose # ", _GetLastError );
return(-1);
}
}
//---- if the alert has not been changed, exit: it is too early for opening a new position
else return(0);
}
}

//+------------------------------------------------------------------+
//| if execution reached this point, there is no an open position |
//| check whether it is still possible to open a position |
//+------------------------------------------------------------------+

//---- if the MACD has met the zero line bottom-up,
if ( NormalizeDouble( MACD_1, Digits + 1 ) > 0.0 &&
NormalizeDouble( MACD_2, Digits + 1 ) <= 0.0 )
{
//---- open a BUY position
if ( OrderSend( Symbol(), OP_BUY, 0.1, Ask, 5, 0.0, 0.0, "MACD_test", 0, 0, Green ) < 0 )
{
_GetLastError = GetLastError();
Alert( "Error OrderSend # ", _GetLastError );
return(-1);
}
return(0);
}
//---- if the MACD has met the zero line top-down,
if ( NormalizeDouble( MACD_1, Digits + 1 ) < 0.0 &&
NormalizeDouble( MACD_2, Digits + 1 ) >= 0.0 )
{
//---- open a SELL position
if ( OrderSend( Symbol(), OP_SELL, 0.1, Bid, 5, 0.0, 0.0, "MACD_test", 0, 0, Red ) < 0 )
{
_GetLastError = GetLastError();
Alert( "Error OrderSend # ", _GetLastError );
return(-1);
}
return(0);
}

return(0);
}

Ok,

I have found an artical that shows how to create the alert, but don't know how to code it.
