error: onstate change method object reference not set to an instance of an object

[traderqz]

i get this error when executing the simple strategy i built from ninjatrade. Please refer to the pics i attached, my strategy is just enter bullish limit order at close price of the candle. I did that with a “if” current candle close is greater than current candle open, which means a bullish candle, enter a buy limit, and a stop loss that is at the low of the current candle

Hello traderqz,

Thank you for your post.

Is this happening specifically when you use this Strategy Builder strategy?

Have you unlocked this script from the Strategy Builder to edit the code in the NinjaScript Editor?

If you test on a new workspace with a blank chart with no templates or indicators, are you still seeing this error?

I look forward to you response.
