Rules of MTF Studies in the Conditional Wizard TSw Editor?

What are the rules pertaining to MTF studies in regard to the Conditional Wizard Think or Swim Editor(CWTSE)?

We know your study MTFMACD_v2 which you gave to us freely can not be referred to because in has a rec statement in it.   Does it have to be frozen, referring only to last bar, tried that?  Time frames all above? they are

But my study, the following, while gets by the compiler,  always fails to execute.

Condition:   ADLMTF10Frozen().longsignal==1

Action: Buy at Mkt , Alert Value Chart looks good.

Why is this?

#ADLMTF10Frozen

input length = 3;

input TradeSize =1;

def    LowestAggregation = GetAggregationPeriod();

def    LowAggregation = AggregationPeriod.HOUR;

def    highAggregation = AggregationPeriod.FOUR_HOURS;

def    highestAggregation = AggregationPeriod.DAY;

declare lower;

def LowestUp = IsAscending (close(period = LowestAggregation), 1) or PriceOsc().PriceOsc > -0.7;

def LowestDown = IsDescending (close(period = LowestAggregation),1)  or PriceOsc().PriceOsc < 0.7;

def LowUp = IsAscending (close(period = LowAggregation)[1], length);

def LowDown = IsDescending (close(period = LowAggregation)[1], length);

def HighUp = IsAscending (close(period = highAggregation), length)[1];

def HighDown = IsDescending (close(period = highAggregation), length)[1];

def HighestUp = IsAscending (close(period = highestAggregation), length)[1];

def HighestDown = IsDescending (close(period = highestAggregation), length)[1];

plot Longsignal = LowestUp && LowUp && HighUp & HighestUp;

longsignal.SetPaintingStrategy(PaintingStrategy.ARROW_UP);

longsignal.SetDefaultColor(Color.CYAN);

longsignal.SetLineWeight(3);

plot ShortSignal = LowestDown && LowDown && HighDown & HighestDown

ShortSignal.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);

ShortSignal.SetDefaultColor(Color.MAGENTA);

ShortSignal.SetLineWeight(3);
