IOGMode vs MarketNextBar

I have IOGMode enable and using MarketNextBar to create long and short order as shown below. However, when I applied it to the chart, an error messgae is pop-ip "The Enabled Intra-bar Order Generation setting is incompatible with Open Next Bar type strategies."

From my understanding, there is no Open Next Bar type strategies below, please advise why there is an error message pop-up!

namespace PowerLanguage.Strategy {

m_linearregvalue1.price = price;
m_linearregvalue1.length = length;

}

Hello lewisthegood,

We have reviewed your code and found out that you are using [CalcAtOpenNextBarAttribute(true)].
This attribute enables Open Next Bar mode, and is not compatible with Intra-Bar Order Generation.
To have your signal work do not use [CalcAtOpenNextBarAttribute(true)] or disable IOG.

im sure im not using [CalcAtOpenNextBarAttribute(true)], and the error message still pop-up

Hi lewisthegood,

Our development team has reviewed the script you shared via email.

The error "The Enabled Intra-bar Order Generation setting is incompatible with Open Next Bar type strategies" keeps popping up because MultiCharts remembered the (true) value set for CalcAtOpenNextBarAttribute during the latest compilation.

Please try to uncomment [CalcAtOpenNextBarAttribute(true)] > set it to False > compile the code > comment [CalcAtOpenNextBarAttribute(false)] out once again. The error should not appear after that.
