EL question--need help intraday programming

Is there a way to make an intraday strategy execute just one time? In other words, say you have a strategy.... it executes, then later it closes the position.....I want to make sure it doesn't execute again...one execution per day then strategy shuts down. Any thoughts?

You could monitor the number of trades and block additional trades for the day when a new trade happens.

You could also use a true/false variable that you use as a flag. When you enter a trade you set this variable to false and reset it on a date change.

Code

if Date <> Date[1] then
TradingAllowed = true;


if TradingAllowed and your other entry conditions are matched then
begin
 Take a trade
TradingAllowed = false;
end;

You might need to change the position where you set the flag to false, to something like

Code

if MarketPosition <> 0 then TradingAllowed = false;

Something like the above should get you started.

ABCTG,

Thanks for help and reply.

The problem I am running into still is that the strategy is missing trades that it should be taking. The problem may be that I am using hourly charts....? Is there any other way to know when a new day has arrived so I can reset the flag?

Using stock tradestation new low function:

Code

[IntrabarOrderGeneration = false]

inputs: int PeriodType( 1 ) ;
{ pass in 1 for chart, 2 for day, 3 for week, 4 for month, 5 for year }

variables: 
	int BT( BarType ),
	int tradecount ( 0 ),
	bool TradingallowedL ( true ),
	bool LastBarOfPeriod( false ), 
	double LowestLo( -1000000 ), { LowestLo is initialized to a large -ve value to 
	 ensure that if a calendar period is specified, the first such period on the 
	 chart is ignored because it may be incomplete }
	bool IsDailyBarOrShorter( false ),
	bool IsWeeklyBarOrShorter( false ),
	bool IsMonthBarOrShorter( false ),
	bool NextBarIsNewDay( false ),
	bool NextBarIsNewWeek( false ),
	bool NextBarIsNewMonth( false ),
	bool NextBarIsNewYear( false ) ;
		
If date<>date[1] then tradingallowedl=true;


if CurrentBar = 1 then
	begin
	IsDailyBarOrShorter = BT <= 2 or BT = 14 ;
	IsWeeklyBarOrShorter = BT <= 3 or BT = 14 ;
	IsMonthBarOrShorter = BT <= 4 or BT = 14 ;
	end ;

NextBarIsNewDay = Date <> Date next bar ;
NextBarIsNewWeek =  DayOfWeek( Date) > DayOfWeek( Date next bar ) ;
NextBarIsNewMonth = Month( Date ) <> Month( Date next bar ) ;
NextBarIsNewYear = Year( Date ) <> Year( Date next bar ) ;

if ( PeriodType = 2 and IsDailyBarOrShorter and NextBarIsNewDay )
	or ( PeriodType = 3 and IsWeeklyBarOrShorter and NextBarIsNewWeek )
	or ( PeriodType = 4 and IsMonthBarOrShorter and NextBarIsNewMonth )
	or ( PeriodType = 5 and IsMonthBarOrShorter and NextBarIsNewYear )
then
	LastBarOfPeriod = true 
else
	LastBarOfPeriod = false ;

if ( CurrentBar = 1 and ( PeriodType <= 1 or PeriodType > 5 ) ) 
	or LastBarOfPeriod[1] 
	or Low < LowestLo 
then
	LowestLo = Low ;
	
	
	
  if LastBarOfPeriod = false and tradingallowedl=true then
  begin
	Sell Short( "NewLo" ) next at bar at LowestLo - 1 point stop ;
	tradingallowedl=false;
    end;

The Red parts above it what I added to the stock new lo from tradestation....just using a simple % pair to exit...

jschultzjr,

you are welcome. Can you show some examples of missed trades and explain why you would expect a trade at these points?

Tradestation has a Function called "Tradestoday", so all you have to do is add the following:
if Tradestoday(date) = 0 then begin
