Moving Average Exponential For ThinkOrSwim

[Joseph H]

Hi everyone,
I am hoping someone could help convert TradingViews EMA code
https://github.com/twopirllc/pandas-ta/issues/519#issuecomment-1104066145
to thinkscript. I am more concerned with getting the smoothing feature implemented.

Hi everyone,
I am hoping someone could help convert TradingViews EMA code
https://github.com/twopirllc/pandas-ta/issues/519#issuecomment-1104066145
to thinkscript. I am more concerned with getting the smoothing feature implemented.

Here is the code:

//@version=5

indicator(title="Moving Average Exponential", shorttitle="EMA", overlay=true, timeframe="", timeframe_gaps=true)

len = input.int(9, minval=1, title="Length")

src = input(close, title="Source")

offset = input.int(title="Offset", defval=0, minval=-500, maxval=500)

out = ta.ema(src, len)

plot(out, title="EMA", color=color.blue, offset=offset)

ma(source, length, type) =>
switch type
"SMA" => ta.sma(source, length)
"EMA" => ta.ema(source, length)
"SMMA (RMA)" => ta.rma(source, length)
"WMA" => ta.wma(source, length)
"VWMA" => ta.vwma(source, length)

typeMA = input.string(title = "Method", defval = "SMA", options=["SMA", "EMA", "SMMA (RMA)", "WMA", "VWMA"], group="Smoothing")

smoothingLength = input.int(title = "Length", defval = 5, minval = 1, maxval = 100, group="Smoothing")

smoothingLine = ma(out, smoothingLength, typeMA)

plot(smoothingLine, title="Smoothing Line", color=#f37f20, offset=offset, display=display.none)

check this..

#//@version=5
#indicator(title="Moving Average Exponential", shorttitle="EMA", overlay=true, timeframe="", timeframe_gaps=true)

input showCloud = yes;
input movAvgType = AverageType.EXPONENTIAL;
input Length = 9;
input Source = close;
input smoothingMaType = AverageType.SIMPLE;
input smoothingLength = 5;
input offset = 0;

def na = Double.NaN;
def last = IsNaN(close);
def out = MovingAverage(movAvgType, Source, Length);
def smoothingLine = MovingAverage(smoothingMaType, out, smoothingLength);

plot emaLine = if last or showCloud then na else out[offset];                # "EMA"
plot smoothEMA = if last or showCloud then na else smoothingLine[offset];    # "Smoothing Line"
emaLine.SetDefaultColor(Color.CYAN);
smoothEMA.SetDefaultColor(Color.LIGHT_RED);

AddCloud(if last or !showCloud then na else out[offset],smoothingLine[offset],Color.DARK_GREEN, Color.DARK_RED, yes);

# end of CODE
