Candle high/low highlighted

Hello

Can someone please help me. Im looking for an indicator where I can highlight specific candles on mt4 on a 15m chart for example the 1am candle to be highlighted from its high to its low and for every candle 2 hours after so it would be 1am,3am,5am,7am,9am,11am and so on.

Thanks

I believe this is good done with MQL5.
Here you can choose e.g. different color arrows can be placed over them.

anyone?
