PeriodHighLow Tradestation indicator Help

[v101 10]

Hello;

I am a newbie at Tradestation development. I am trying to develop a simple indicator so I can input overnight start times and overnight end times and have Tradestation plot the high and low from this time period. 

 

I have tried a few different ways, having some success, but not doing exactly what I want. 

 

Here is the first code I tried to develop:

Inputs:    Starttime (1630),
        EndTime ( 0930);
        
        
Vars:    PeriodHigh(0),
        LastPeriodHigh (0),
        PeriodLow(999999),
        LastPeriodLow (999999);
        
If T > Starttime and T < EndTime then
Begin
    If H > PeriodHigh then PeriodHigh = H;
    If L < PeriodLow then PeriodLow = L;
    End;
    

Plot1( PeriodHigh );
Plot2( PeriodLow );
 

This seems to work, but doesn't catch the Low's for some unknown reason see the screen shot. PLOT1 appears to have caught the HIGH, but PLOT2 isn't correctly plotting the time period LOW. 

So I modified some other code I have and tried indicator version2 a bit different, but here is what I tried doing:

 

inputs:
    int ONightStart( 1630 ),    //The start time of user defined session
    int ONightEnd( 0930 ),        //The end time of a user defined session
    OverNightSession(1),        // Plot overnight session HIGH / LOW
    OffSetF(.0005), 
    LookBack(25);

vars:
    Var0( 0),
    bool ONightSession( False ), // True when in Overnight Session
    bool InSession( False );    // True when in session

begin
    ;
    ;
    Var0 =  CLOSE  * OffSetF;
    If T > ONightStart and T < ONightEnd then ONightSession = True;
    Begin
    
        If OverNightSession = 1 and ONightSession = True then  begin
            If HIGHD( 0) <= HIGHEST( HIGH  + Var0, LookBack) and HIGHD( 0) >= LOWEST( LOW  - Var0, LookBack) then  PLOT2 (HIGHD( 0), "OvernightHigh");
            If LOWD( 0) <= HIGHEST( HIGH  + Var0, LookBack) and LOWD( 0) >= LOWEST( LOW  - Var0, LookBack) then  PLOT3 (LOWD( 0), "OvernightLow");
            end;

 

However when I try to apply this, I get nothing on the screen. Is this because I am trying to use the HIGHD keyword? is the reason it plots nothing because the session time, doesn't have the HIGHD data?

 

Any help is appreciated.

Hi,

StartTime(1630) // 430 PM

EndTIme(930) // 930 AM

If T > ONightStart and T < ONightEnd then ONightSession = True; 

Time cannot be greater than 430 PM less than 930 AM(since we haven't mentioned any Date).

Try this:-

If T > ONightStart OR T < ONightEnd then ONightSession = True; 

 

Goodluck.
