You can code an indicator that only updates at the start of each new 4 hour candle. This gives a stepped result.

Here is an example for a 4 hour 20MA. If you increase the stored variables to 200 and then divide the sum of them by 200 you will have a 200MA. I got bored with the typing after 20 so I’ll leave the rest up to you!

Obviously you will need to make sure that your chart has at least 200 4 hour closes on it. A 10k 15 minute chart has over 3200 on it so you should be good to go. Happy typing and share the result here when you finish it please!

Making it update every fifteen minutes would be a coding nightmare and probably very slow to draw so I think this stepped MA is about as good as it gets. If it is just an indicator on a chart rather than a value from an indicator that you want then Nicolas’ MTF idea will probably suit you better.

if opentime = 000000 or opentime = 040000 or opentime = 080000 or opentime = 120000 or opentime = 160000 or opentime = 200000 then
a1 = a2
a2 = a3
a3 = a4
a4 = a5
a5 = a6
a6 = a7
a7 = a8
a8 = a9
a9 = a10
a10 = a11
a11 = a12
a12 = a13
a13 = a14
a14 = a15
a15 = a16
a16 = a17
a17 = a18
a18 = a19
a19 = a20
a20 = open
endif

if a1 <> 0 then
ave20 = (a1+a2+a3+a4+a5+a6+a7+a8+a9+a10+a11+a12+a13+a14+a15+a16+a17+a18+a19+a20) / 20
else
ave20 = undefined
endif

return ave20
