AddChart bar colors not set

[yuvalw]

Hi,

I have the following simple script that adds a chart as a study on the lower pane, problem is that all bar colors are the same - PINK
What are exactly the growColow / fallColor / neutralColor ? The "addChart" function is not documented so it's hard to know...

Thanks.

declare lower;

input Symbol =  "$ADSPD";
input ChartType = ChartType.CANDLE;
input PriceType = "Last";
input Timeframe = AggregationPeriod.THREE_MIN;

def h = high(symbol = Symbol, period = Timeframe, PriceType = PriceType);
def l = low(symbol = Symbol, period = Timeframe, PriceType = PriceType);
def o = open(symbol = Symbol, period = Timeframe, PriceType = PriceType);
def c = close(symbol = Symbol, period = Timeframe, PriceType = PriceType);

AddChart(High = h, Low = l, Open = o, Close = c, Type = ChartType, growColor = Color.PINK, fallColor = Color.BLUE, neutralColor = Color.BLUE );

Here is how it looks:

@yuvalw Here is working code... With the AddChart() function being deprecated, and with virtually no documentation, we sometimes have to find workarounds... A major portion of the working code comes from some test code I had kicking around...

Edited to add: It should be noted that using an alternate timeframe from that of the Chart will not work properly so the AggregationPeriod code could be removed...

declare lower;

input Symbol =  "$ADSPD";
input ChartType = ChartType.CANDLE;
input PriceType = "Last";
input Timeframe = AggregationPeriod.THREE_MIN;

def h = high(symbol = Symbol, period = Timeframe, PriceType = PriceType);
def l = low(symbol = Symbol, period = Timeframe, PriceType = PriceType);
def o = open(symbol = Symbol, period = Timeframe, PriceType = PriceType);
def c = close(symbol = Symbol, period = Timeframe, PriceType = PriceType);

# Candle/Bar trend direction logic
def UpCandle = close > open;
def DnCandle = close < open;
def doji = close == open;

# GlobalColor Colors

DefineGlobalColor("UpCandle", Color.GREEN);
DefineGlobalColor("DnCandle", Color.RED);
DefineGlobalColor("Doji", Color.WHITE);


# Paint Candles using separate AddChart() function calls

AddChart(high = if UpCandle then l else Double.NaN, low = h, open = c,  close = o, type = ChartType, growcolor = GlobalColor("UpCandle"));

AddChart(high = if DnCandle then h else Double.NaN, low = l, open = o,  close = c, type = ChartType, growcolor = GlobalColor("DnCandle"));

AddChart(high = if doji then h else Double.NaN, low = l, open = o,  close = c, type = ChartType, growcolor = GlobalColor("Doji"));

in my experimenting with addchart(), only the growColor parameter seems to work.
so if you want different colors, you need an addchart for each color.
