How to access the second if statement - trading

Question

I am totally drain out as the second if statement couldn't be executed.
My original idea was when volatility is in a range of 90 - 110, the program will send one and only one order. And it will wait and see till the volatility reaches in a range of 111 - 150, and then it will send the second order.
If I don't use a bool function here, the program will send countless order when the range is reached.
Could someone please help me?
if ( TodayMaxVolatilityPercentage >= 90.0
&& ( dayTrend == 1 )
&& orderOpened == false
)
{
Print( "Entered if clause" );
// Print( "Today volatility percentage is: ", TodayMaxVolatilityPercentage + "%" );
// ticket: Returns number of the ticket assigned to the order by the trade server or -1 if it fails.
ticket = OrderSend( Symbol(),
OP_SELL,
0.3,
Bid,
3,
0 * MyPoint,
30 * MyPoint,
NULL,
MagicNumber,
0,
Blue
);
Print( "Order is opened on", OrderOpenTime()+" at price: ", OrderOpenPrice() );
Print( "trend number is ",dayTrend );
if ( ticket > 0 )
{
if ( TakeProfit > 0 ) TheTakeProfit = Bid - TakeProfit * MyPoint;
OrderSelect( ticket, SELECT_BY_TICKET ); // bool value
/* OrderModify( OrderTicket(),
OrderOpenPrice(),
0,
NormalizeDouble( TheTakeProfit, Digits ),
0,
Green
);
*/
}
orderOpened = true;
if ( TodayMaxVolatilityPercentage >= 110.0 ) orderOpened = false;
}
if ( TodayMaxVolatilityPercentage >= 110.0
&& ( dayTrend == 1 )
&& orderOpened == false
)
{
Print( "Entered second if clause" );
// ticket: Returns number of the ticket assigned to the order by the trade server or -1 if it fails.
ticket = OrderSend( Symbol(),
OP_SELL,
0.3,
Bid,
3,
0 * MyPoint,
30 * MyPoint,
NULL,
MagicNumber,
0,
Blue
);
if ( ticket > 0 )
{
if ( TakeProfit > 0 ) TheTakeProfit = Bid - TakeProfit * MyPoint;
OrderSelect( ticket, SELECT_BY_TICKET ); // bool value
/* OrderModify( OrderTicket(),
OrderOpenPrice(),
0,
NormalizeDouble( TheTakeProfit, Digits ),
0,
Green
);
*/
}
orderOpened = true;
}

A hidden show-stopper:
By design, the first successful OrderSend() returns a value you assign into an ticket = OrderSend(...).
The devil is hidden in detail.
[MQL4-Help] says:
Returns number of the ticket assigned to the order by the trade server or -1 if it fails.
So the first successful OrderSend() ticket# returned is 0 ( in StrategyTester, a real MT4/Server rather runs into high numbers drawn from it's db.pool of tickets ).
Thus the second if ( ticket > 0 ) will never let you in.
It is common to rather use if ( ticket > EMPTY ) so as to also clarify the intention and use symbolic instead of a -1 integer constant.
