QUESTION

I'm trying to set a strategy and need to get the previous EMA value, how can I do that ? I'm not a skilled programer. I tried but it doesn't seems to work.
I´v tried this two ways.

1)
var prevema_15m = parseFloat(chart15m[chart15m.length - 3].close)
var ema8_15m = bp.indicators.ema(prevema_15m, 8)
_____________
2)
var ema8_15m = bp.indicators.ema(chart15m[chart15m.length - 3].close, 8)

If some have any idea. I'll be very grateful.
