TradeStation will get confused with this approach if you start adjusting the chart's timeframe. It's also important that you set the second chart's timeframe before you add the secondary time frame. You may also want to confirm that both data streams on the same chart are aligned with the same start date using the First Date option on the Format Symbol / Settings tab.
For example, if you're trying to use a 50 EMA of daily data on a 30-minute chart, make sure you're loading enough data for 50 days on the daily secondary data stream. IMPORTANT: If you try the approach listed and you're sure you've got everything set correctly and they're not aligning properly, check that you're loading enough data on your timeframes to complete the EMAs.
For example, you may want to see the 8 EMA of the Daily on your Hourly chart. The following video shows how you can add an EMA from another timeframe onto your chart in TradeStation without using any special indicators.
