I think the error is due to the presence of curly braces that the formatting system interprets as placeholders. To fix it, escape your braces or ensure the string passed to the logging/printing function doesn’t contain unintended formatting tokens.
Maybe it will help:
var jsonString = Account.ToJSON();
jsonString = jsonString.Replace("{", "{{").Replace("}", "}}");
Print("[OnStart] Account:\n" + jsonString);@EDG777

What TradingView functions are you using? If it’s a strategy or indicator set to execute at the close of each bar, I’ve converted things like EMA and ATR calculations—so that they operate the same way, only at bar close.
