Bongo Indicator For ThinkOrSwim

I was able to Re-Create the BONGO indicator, using Wilders RSI. Even though, Wilders RSI isn't available via TOS, I was able to use that same data and code to re-create the indicator. Also re-created the BONGO Weekly, it plots the weekly even on lower time frames. Comes in handy..

Here is the code for the Bongo Indicator.

The Bongo Indicator is a trend-following momentum indicator that uses a stacked configuration of three Wilder's RSI periods (8, 14, 19) combined with a 9-period Simple Moving Average to identify sustained directional moves suitable for day trading.

The Bongo Indicator excels at keeping day traders on the right side of momentum.
Its "sticky" nature (holding signal until opposite condition) reduces noise and premature exits.

Best results come from using it as a directional filter while entering on pullbacks with proper risk management.

Always combine with higher timeframe analysis and review overall market conditions.
Ruby:
def RSI8 = RSI(length = 8);
def RSI14 = RSI(length = 14);
def RSI19 = RSI(length = 19);
def MA9 = SimpleMovingAvg(close, 9);

def Up = if (RSI8 > RSI14 and RSI14 > RSI19 and close > MA9) then 1 else 0;
def Dn = if (RSI8 < RSI14 and RSI14 < RSI19 and close < MA9) then 1 else 0;

# Extended Signals (hold signal until opposite condition)
def BongoUp = if Up then 1 else
              if Dn then 0 else BongoUp[1];

def BongoDn = if Dn then 1 else
              if Up then 0 else BongoDn[1];


declare lower;
plot UpZone = if BongoUp then 1 else 0;
plot DnZone = if BongoDn then 1 else 0;


UpZone.SetPaintingStrategy(PaintingStrategy.SQUARED_HISTOGRAM);
UpZone.SetDefaultColor(Color.dark_GREEN);
UpZone.SetLineWeight(5);
UpZone.HideTitle();
UpZone.HideBubble();

DnZone.SetPaintingStrategy(PaintingStrategy.SQUARED_HISTOGRAM);
DnZone.SetDefaultColor(Color.dark_RED);
DnZone.SetLineWeight(5);
DnZone.HideTitle();
DnZone.HideBubble();


plot ZeroLine = 0;
ZeroLine.SetDefaultColor(Color.GRAY);
ZeroLine.SetStyle(Curve.SHORT_DASH);
ZeroLine.HideTitle();
ZeroLine.HideBubble();

# Add background cloud effect (optional - can be disabled)
AddCloud(UpZone, 0, Color.DARK_GREEN, Color.CURRENT);
AddCloud(DnZone, 0, Color.DARK_RED, Color.CURRENT);

@MIc5th Good news. Yes, the ToS RSI() uses a default Wilders Average
