RSI oversold after 9 ema crosses below VWAP

I moved your post out of the "Strategy Guide" topic and into the "Stock Scanners" topic. There were no AddOrder() statements in the code and nothing in your question mentioned trying to use this to build a chart strategy.

I also updated the title of the question to include some very important details your original was lacking.

This cannot be completed using just the Condition Wizard. The reason for this is there is no method in the Condition Wizard to specify "at least 30 bars ago". So we must break things out into separate variable statements and then assemble the individual pieces to derive the final output you have specified.

I tried to retain as much of your original code as possible so you can follow along and note the changes.

input minimumBarsBack = 30;
def condition = MovAvgExponential().”AvgExp” crosses below reference VWAP().”VWAP”;
def trigger = RSI().”RSI” crosses above 28;
plot scan = Highest(condition, minimumBarsBack) < 1 and trigger;
