While doing back testing for glenmark eq for last 6 days on 30mins time frame chart for SMA 5 & 13 cross over it is not giving any singnals but on the google cgart of 30 mins i can see the cross over

signals will be generated only when the condition matches, you can verify the EMA crossover by applying the same EMA’s on the chart manually and can check if crossover happening or not.
