Charting Software Question(Dynamic MA lines)

Hi folks

Could anybody please tell me which charting software will let me place dynamic horizontal lines on intraday charts that can be set to the value of weekly and daily moving averages.

Am currently using Prorealtime and unfortunately this CANNOT be programmed as an indicator with their software which is pi**ing me right off.

Regards

I use TradeStation and you can write indicators to draw trend lines, horizontal lines etc. Have a look at my vwap engine journal and you'll see dynamic horizontal lines.
