Simple ThinkScript Strategy to Pine Script - No Trades Placed

I'm converting a simple ThinkScript strategy to Pine Script. In ThinkScript, it opens many trades over the past few days (5-minute chart on SPY ticker), but when translated to Pine Script, there are no trades placed. Wondering if someone can spot the bug. Note, it uses request.security to get data from a higher timeframe/aggregation, not sure if that's the issue or not.

This is the ThinkScript:

input agg = AggregationPeriod.HOUR; input TrendPeriods = 5;input use_trading_hours = yes;input spread = 0.15;####################################################### TIME######################################################def startTradingTime = if use_trading_hours == yes then 0930 else 0000;def noMorePositions = if use_trading_hours == yes then 1530 else 0000;def endTradingTime = if use_trading_hours == yes then 1600 else 0000;def isTradingSession = if use_trading_hours == yes then SecondsFromTime(startTradingTime) >= 0 and SecondsTillTime(endTradingTime) > 0 else yes;def positionsStillAllowed = if use_trading_hours == yes then SecondsTillTime(noMorePositions) > 0 else yes;def h = high(period = agg); def l = low(period = agg); def c = close(period = agg); def hh = highest(h, trendPeriods); def ll = lowest(l, trendPeriods); def trend = if ((c - ll) / (hh - ll)) > .5 then 1 else 0; // Enter long (flip from short if necessary)addorder(orderType.BUY_AUTO, trend[1] and isTradingSession and positionsStillAllowed and BarNumber()>1, tradesize=1, price=open[-1]+spread); // Exit long at EODaddorder(orderType.SELL_TO_CLOSE, !isTradingSession[-1], tradesize=1, price=open-spread); // Enter short (flip from long if necessary)addorder(orderType.SELL_AUTO, !trend[1] and isTradingSession and positionsStillAllowed and BarNumber()>1, tradesize=1, price=open[-1]-spread); // Exit short at EODaddorder(orderType.BUY_TO_CLOSE, !isTradingSession[-1], tradesize=1, price=open+spread);

Due to looking at higher aggregation/timeframe, I use trend[1] to get the previous, fully closed trend value to act on the current bar re: repainting.

This is my Pine Script so far that generates no trades in the Strategy Tester, yet shows no syntax or compile errors:

Note that if you comment out the RTH/InSession logic from the entry/exit conditions, it opens 1 trade, however I'm trying to get a 1:1 match from ThinkOrSwim, and it trades almost daily over the past few weeks. Can you spot the issue?
