How to make strategy close out a trade near end of day Friday same week trade entered?

I have a strategy backtester I am using, The strategy I am using is for credit spreads. I am wondering is there a way to setup a buy to close or sell to close code that will close out the trade at the closing price on Friday? The friday closing price immediately after trade entry? Would be amazing help! I have the whole rest of the code just need to close out the trades at the closing price on the closest Friday to trade entry, even if its just a 1 day trade. and the strategy backtester should calculate my PL based on if I bought shares when I have the signal to buy shares and then I will sell them at the closing price on the immediate Friday closing price after trade entry.

AddOrder(SELL_TO_CLOSE, "close out the shares purchased immediately at the next Friday closing price"

what is in quotes is what i am not sure how to code, hopefully this is a quick fix, thanks for any help!

Easiest way should be:
Ruby:
condition = GetDayofWeek(GetYYYYMMDD()) == 5 and SecondsTillTime(1600) == 0
This should have it sell on Friday at 4 p.m. if you were in a long trade.
okay it works on all trades, except for some reason whenever my strategy gives a signal to trade on a friday, meaning it enters the trade on a monday, then it closes the trade out on monday same day. IDK why that is, is there a way to fix that or a way to exclude trade entries on mondays

oh okay now I see if it enters a trade on a Friday it just closes it out at the monday open, can I just exclude monday entries?

also some weeks are holidays and dont have 5 trading days so then it keeps the trade open for another week until friday close, also it often likes to close out trades at the open price on monday even if not opened on friday

If I am trying to test a swing trading strategy in a backtester in TOS, and i want the position closed out on the last trading day of the week at market close, can someone help me figure this out:

If I use this as the exit condition, then it works unless:
1. there is less than 5 days in that week due to holiday or day off then trade stays open for another week and closes out on the next week friday close
2. the trade is opened on Friday - it closes out the trade at the price of Monday open instead of friday close
3. if the trade is opened on a monday - it closes out the trade same day at the price of the previous friday close instead of the friday close upcoming.

this is what I am using now:

def condition = GetDayofWeek(GetYYYYMMDD()) == 5 and SecondsTillTime(1600) == 0;
AddOrder(OrderType.SELL_TO_CLOSE, exitcondition);

Any ideas on how to fix this so I can backtest a variety of strategies I have written for swing trading?
Just need the backtester to reliably close out the trade at the closing price on the last day of trading each week, no matter what day the trade is opened and even if there are less than 5 days in a trading week sometimes. I want these trades to be closed lined up with the last day of each week: the options expiration cycle expiration date
