Using ATR to Create Profit Target

[TreeDT]

I've been working on trying to reverse the ATRTrailingStop and create ATRTrailingProfit. I have put the following code together, but it's not plotting anything. What have I done wrong? Anyone have any ideas?

input trailType = {default modified, unmodified};
input ATRPeriod = 5;
input ATRFactor = 3.5;
input firstTrade = {default long, short};
input averageType = AverageType.WILDERS;

Assert(ATRFactor > 0, "'atr factor' must be positive: " + ATRFactor);

def HiLo = Min(high - low, 1.5 * Average(high - low, ATRPeriod));
def HRef = if low <= high[1]
    then high - close[1]
    else (high - close[1]) - 0.5 * (low - high[1]);
def LRef = if high >= low[1]
    then close[1] - low
    else (close[1] - low) - 0.5 * (low[1] - high);

def trueRange;
switch (trailType) {
case modified:
    trueRange = Max(HiLo, Max(HRef, LRef));
case unmodified:
    trueRange = TrueRange(high, close, low);
}
def target = ATRFactor * MovingAverage(averageType, trueRange, ATRPeriod);

def state = {default init, long, short};
def trail;
switch (state[1]) {
case init:
    if (!IsNaN(target)) {
        switch (firstTrade) {
        case long:
            state = state.long;
            trail =  close + target;
        case short:
            state = state.short;
            trail = close - target;
        }
    } else {
        state = state.init;
        trail = Double.NaN;
    }
case long:
    if (close < trail[1]) {
        state = state.long;
        trail = Max(trail[1], close + target);
    } else {
        state = state.short;
        trail = close - target;
    }
case short:
    if (close > trail[1]) {
        state = state.short;
        trail = Min(trail[1], close - target);
    } else {
        state = state.long;
        trail =  close + target;
    }
}

def BuySignal = Crosses(state == state.long, 0, CrossingDirection.ABOVE);
def SellSignal = Crosses(state == state.short, 0, CrossingDirection.ABOVE);

plot TrailingTarget = trail;

TrailingTarget.SetPaintingStrategy(PaintingStrategy.POINTS);
TrailingTarget.DefineColor("Buy", GetColor(0));
TrailingTarget.DefineColor("Sell", GetColor(1));
TrailingTarget.AssignValueColor(if state == state.long
    then TrailingTarget.Color("Sell")
    else TrailingTarget.Color("Buy"));

Go into the studies setting panel and switch the TrailingTarget Values from Numerical to Boolean...

Just remember that switching something on or off requires a boolean... Displaying data on a chart requires numerical data...

Edited to Add: I may have answered prematurely... The power was out here for 7 hours due to severe wind and thunderstorms and I was just trying to get caught up before heading off to bed... I may have misconstrued what, exactly, you are trying to accomplish... If that is the case then more tweaking may be required but I will wait to hear back...
