Could you please help with error? I'm new to programming. I have selected the custom indicator in the "Manage References"
Error CS0103: The name 'pvto' does not exist in the current context

Can you please post the complete cBot code as well as the indicator code so that we can reproduce this issue?

Hi Panagiotis,
I've updated the initial post.

Hi peetman23,
You need to change
public Indicator pvto;
to
public PriceVolumeTrend_Optimized pvto;
and
// Put your core logic here
if (pvto(LastResult) < -9)
{
Close(TradeType.Sell);
Open(TradeType.Buy);
}
else if (pvto(LastResult) > 9)
{
Close(TradeType.Buy);
Open(TradeType.Sell);
}
to
// Put your core logic here
if (pvto.PVTO.LastValue < -9)
{
Close(TradeType.Sell);
Open(TradeType.Buy);
}
else if (pvto.PVTO.LastValue > 9)
{
Close(TradeType.Buy);
Open(TradeType.Sell);
}
for the cBot to build.
Best Regards,
Panagiotis

Thank you. I was able to build the cBot, but when I try to backtest it throws the following:
Crashed in OnTick with NullReferenceException: Object reference not set to an instance of an object.

Hi peetman23,
There are many issues in your code like the fact that the indicator needs be initialized in OnStart (Initialize is not used anywhere in the cBot), correct parameters are not passed to the indicator and volume seems really wrong. You need to fix all these issues and any others that might be there before the cBot starts working properly.
