Can someone look at this code and see why Im getting an error? Thanks in Advance....
Code:
#Script changes background color based on MTF of the ATR Trailing stop
#
#
script SuperTrend {
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 loss = ATRFactor * MovingAverage(averageType, trueRange, ATRPeriod);
def state = {default init, long, short};
def trail;
switch (state[1]) {
case init:
if (!IsNaN(loss)) {
switch (firstTrade) {
case long:
state = state.long;
trail = close - loss;
case short:
state = state.short;
trail = close + loss;
}
} else {
state = state.init;
trail = Double.NaN;
}
case long:
if (close > trail[1]) {
state = state.long;
trail = Max(trail[1], close - loss);
} else {
state = state.short;
trail = close + loss;
}
case short:
if (close < trail[1]) {
state = state.short;
trail = Min(trail[1], close + loss);
} else {
state = state.long;
trail = close - loss;
}
}
def BuySignal = Crosses(state == state.long, 0, CrossingDirection.ABOVE);
def SellSignal = Crosses(state == state.short, 0, CrossingDirection.ABOVE);
plot TrailingStop = trail;
TrailingStop.SetPaintingStrategy(PaintingStrategy.POINTS);
TrailingStop.DefineColor("Buy", GetColor(0));
TrailingStop.DefineColor("Sell", GetColor(1));
TrailingStop.AssignValueColor(if state == state.long
then TrailingStop.Color("Sell")
else TrailingStop.Color("Buy"));
}
input agg1 = AggregationPeriod.MIN;
input agg2 = AggregationPeriod.FIVE_MIN;
input agg3 = AggregationPeriod.THIRTY_MIN;
def SuperT1 = close > SuperTrend(agg = agg1);
def SuperT2 = close > SuperTrend(agg = agg2);
def SuperT3 = close > SuperTrend(agg = agg3);
def green = SuperT1 + SuperT2 + SuperT3;
AssignBackgroundColor(if green == 3 then Color.LIGHT_GREEN else if green == 0 then Color.PINK else Color.WHITE);
