Extended hours price compared to regular session close

[Trader4444]

I'm attempting to do something simple but as usual, seems to be more difficult than I assumed. I simply want to scan during the extended hours to look for stocks moving up or down. I want to use the close of the regular session - the current price during the extended hours session and see that difference either up or down. Also, a minimum of 20,000 in volume in the extended session. I never got passed how to configure for the price move so never attempted the volume. I'm getting a secondary period not allowed: Day error showing. This is all I have. Don't rip on me too bad Thanks

def length =1;
def displace = 0;
def aggregationperiod1 = AggregationPeriod.dAY;

def priceclose = close(period = aggregationPeriod1);
def MovAvg1 = simpleMovingAvg(close[-displace], length);

def q = MovAvg1 - priceclose;
plot result = q;

I was trying to do the same. I came up with this, maybe it will help you. Use 1m script aggregation and check the Include Extended box.

#Premarket move
#uses close of week because a week cannot fit into extended hours, this may cause loss of some weekly option values
def WeekClose = Close(period = (AggregationPeriod.Week)); #Close of last full week
def MinClose = Close; #1 min last extended close

def WeekCloseFix = CompoundValue(1, if IsNaN(WeekClose) then WeekCloseFix[1] else WeekClose, WeekClose); #returns a good regular session close

plot PreMarketMove = Round(MinClose-WeekCloseFix,2);

PreMarketMove.AssignValueColor(if PreMarketMove > 0 then Color.UPTICK else if PreMarketMove < 0 then Color.DOWNTICK else GetColor(7));

try this for the rth close minus the current close (it will use the last bar on the chart as the close so if you are not in ext hours it will just use the last bar you see on the screen)

SET TO 1 MIN AGGREGATION

Declare Lower;
input start_time = 1559;
input endtime = 1600;
def selected_time = if SecondsFromTime(start_time) >= 0 and SecondsFromTime(endtime) <
0 then 1 else 0;
def EndClose = if selected_time then close else  EndClose[1];
plot Condition1 =EndClose - Close;

for the other half of your request
you stated :
"a minimum of 20,000 in volume in the extended session"
a minimum of 20k volume TOTAL in the entire ext session or 20K volume just the last bar?
