Hi, i am interested in creating a better way to spot moving average crossover on the 5 min as i usually miss to recognize in real time when the 9 and 20 ema cross on either 5 min or 1 min. Can someone please tell me if it is possible for me to create a PCF where in if the 9ema crosses over 20 it colours the difference between the 9 and 20 green and red vice versa. Thanks appreciate any help.

You may wish to review the following.

That said, I would be very tempted to just add a MACD 9,20 (not the MACD Histogram) to the chart and maybe change the Plot Style to Histogram or Area.
