new contractCPD function crashes in main() at bar 0

Hi,
I don't seem to be able to trace what's wrong here. The new contractCPD function (as explained on the financial-hacker's new blog) seems to be crashing with the below message, here is the diagnostic information. I can't get more details from the contractCPD function...

I am using the script as it is from the 2018 repository and have data subscription to the followings:

CME Real-Time
COMEX Real-Time
IEX Depth of Book
NYSE Arca Options
US Equity and Options Add-On Streaming Bundle
US Reg NMS Snapshot
US Securities Snapshot and Futures Value Bundle

Here is the trace information:

Any help would be much appreciated.

And yes, I am using Zorro 2.01.6.

Post your script.

// Get today's market sentiment //////////////////////////////////////

void main()
{
Verbose = 31;
if(version() < 1.98 || !is(TRADEMODE) || Broker != "IB") {
printf("Need Zorro 1.99+ in IB Trade Mode!");
return;
}
StartDate = NOW;
LookBack = 0;
assetList("AssetsIB");
asset("SPY");

// load today's contract chain
contractUpdate(0,0,CALL|PUT);
printf("n%i contracts today",NumContracts);
if(!NumContracts) return;

// get min and max strike
contract(CALL,45,0);
var StrikeMin = ContractStrike;
contract(CALL,45,9999);
var StrikeMax = ContractStrike;
printf("nStrike range %.2f...%.2f",StrikeMin,StrikeMax);

// get underlying price
var Price,Current = priceClose(0);
printf("nCurrent price %.2f",Current);

// plot CPD histogram
printf("nWait time approx %i minutes",1+NumContracts/200);
contractCPD(45);
int N = 0;
for(Price = 0.75*Current; Price <= 1.25*Current; N++,Price += 0.01*Current) {
if(N == 25)
plotBar("Current",N,floor(Price),cpd(Price),BARS|LBL2,BLACK);
else
plotBar("CPD",N,floor(Price),cpd(Price),BARS|LBL2,RED);
}
printf("nExpected price %.2f",cpdv(50));
}

Zorro beta 2.01 had a bug when retrieving price quotes from the broker. This could be probably the reason of the crash. Please wait for the next beta version 2.02, then test again. If it then still crashes, please post again and I'll look into it.

Thanks! Will do!
