Intraday SMA-EMA Crossover

Algos, strategies, code
1

I would be grateful if someone helps me with this intraday crossover code or gives me the link if already done (or location in Pi menu). I wish to use two moving averages: the 10-min SMA and the 30-min EMA. If colour coding of the line is possible then I wish to see SMA in blue and EMA in red colour

​Regards
