Error on calling OnBarUpdate method on bar 50

[ArcticBiscuit]

Hello All,

I have recently encountered a problem where my code is not running as I run into an error that reads: "Error on calling OnBarUpdate method on bar 0"

I do have a fold loop in the code but I thought I took all necessary precautions to squash any bugs.
Compared to other coding languages, I am relatively new to C#, and this portion of my development is very confusing.

I have included my code here:

protected override void OnBarUpdate()
{
if (BarsInProgress != 0)
return;
if (CurrentBars[0] < LengthCCI)
return;
else
{
if (CurrentBar == 0)
Value[0] = 0;
else
{
double input0 = Input[0];
double high0 = High[0];
double low0 = Low[0];

ATRval = ATR(ST_nATR)[0];
ATRCCI = (ATR(LengthATR)[0]) * AtrFactor;

UP = ((high0)+(low0))/2 + (ST_Atr_Mult * ATRval);
DN = ((high0)+(low0))/2 + ((-(ST_Atr_Mult)) * ATRval);

// CCI_ATR measures distance from the mean. Calculates a trend
// line based on that distance using ATR as the locator for the line.

bar = CurrentBars[0];

price = (Close[0] + Low[0] + High[0]);

//This is for calculating LinDev
double x_bar = ((SMA(High, LengthCCI))[0]+(SMA(Close, LengthCCI)[0])+(SMA(Low, LengthCCI)[0]));
for(int i = 0; i < LengthCCI; i++)
{
TAD[0] = TAD[1] + Math.Abs((High[i]+Low[i]+Close[i])-(x_bar));

if (LengthCCI > 0)
lindev = (TAD[0]/LengthCCI);
else
lindev = 0;
}

//ATR vals

ATRval = ATR(ST_nATR)[0];
ATRCCI = (ATR(LengthATR)[0]) * AtrFactor;

if (Close[0] < ST[1])
{
ST[0] = UP;
}
else
{
ST[0] = DN;
}

if (lindev == 0.0)
{
myCCI = 0;
}
else
{
myCCI = ((price - x_bar) / lindev / 0.015);
}

if (myCCI > 0)
{
MT1[0] = (Math.Max(MT1[1], Median[0] - ATRCCI));
}
else
{
MT1[0] = (Math.Min(MT1[1], Median[0] + ATRCCI));
}

// Alignment of Supertrend and CCI ATR indicators
if ((Close[0]> ST[0]) & (Close[0] > MT1[0]))
{
Stade[0] = (StateUp);
}
else if ((Close[0] < ST[0]) & (Close[0] < MT1[0]))
{
Stade[0] = StateDn;
}
else
Stade[0] = Stade[1];
/*newState = HighestAll(if State <> State[1] then bar else 0);*/
if ((Stade[0] != Stade[1]))
newState = CurrentBar;
else
newState = 0;
// Combined Signal Approach - Supertrend and ATR CCI

if (bar >= newState)
{
CSAplot[0] = MT1[0];
Print(CSAplot[0]);

}
else
{
CSAplot[0] = Double.NaN;
Print(CSAplot[0]);
}


/* Buy/Sell Arrows */
if ((Stade[0] == StateUp) & (Stade[1] != StateUp))
{
BuySignalArrow[0] = (0.998 * MT1[0]);

}
else
{
BuySignalArrow[0] = Double.NaN;
}

if ((Stade[0] == StateDn) & (Stade[1] != StateDn))
{
SellSignalArrow[0] = (1.002 * MT1[0]);

}
else
{
SellSignalArrow[0] = Double.NaN;

}

}

Hello ArcticBiscuit

The error states that it happened on the first bar so you would need to figure out which specific line is throwing the error. You can start by commenting out the later lines of code in OnBarUpdate so you can further isolate the specific line.

This could relate to your initial if conditions with the else, generally the code you have should look like this:

protected override void OnBarUpdate()
{
if (BarsInProgress != 0)
return;

if (CurrentBars[0] < LengthCCI)
{
Value[0] = 0; // set 0 on all bars before LengthCCI
return;
}

double input0 = Input[0];
double high0 = High[0];
double low0 = Low[0];
