OSCAR Oscillator For ThinkOrSwim


Well-known member
Maybe something like this... didn't do all the smoothing options, but you can add them as you need fairly easily:
declare lower;

input type_one = {sma, ema, default wma, hma};

input type_two = {sma, ema, default wma, hma};

input source = close;
input len = 8;
input slow_len = 16;
input crossSignalSensitivity = 2.5;

script osc {
    input source = close;
    input len = 10;

    def A = highest(source, len);
    def B = lowest(source, len);
    plot Oscar_Rough = ((source - B) / (A - B)) * 100;
    def Oscar1 = (Oscar_Rough[1] / 3) * 2;
    def OscarThird = Oscar_Rough / 3;
    plot Oscar = Oscar1 + OscarThird;

def t_fast = osc(source, len).Oscar_Rough;

plot oscar;
switch (type_one) {
    case sma:
        oscar = simpleMovingAvg(t_fast, len);
    case ema:
        oscar = expAverage(t_fast, len);
    case wma:
        oscar = WildersAverage(t_fast, len);
    case hma:
        oscar = hullMovingAvg(t_fast, len);

def t_signal = osc(source, len).Oscar;
plot signal;
switch (type_two) {
    case sma:
        signal = simpleMovingAvg(t_signal, len);
    case ema:
        signal = expAverage(t_signal, len);
    case wma:
        signal = WildersAverage(t_signal, len);
    case hma:
        signal = hullMovingAvg(t_signal, len);
def crossSensitivity = max(oscar, signal) - min(oscar, signal);

plot buy = if oscar crosses above signal AND crossSensitivity > crossSignalSensitivity then signal else double.nan;

plot sell = if oscar crosses below signal AND crossSensitivity > crossSignalSensitivity then signal else double.nan;

plot lower = 20;

plot upper = 80;

Happy Trading,
