Historic Interval Data not Displayed

[richthomas]

I have a simple study that I run for QLD,30 that displays the ema(5,high), ema(5,low), ema(50,hlc3) of the 30 minute, day and week intervals.

My problem is that there is limited historical data displayed for the weekly and daily intervals. There is 30 min data available from 6/22/06.

The daily ema50 only displays to 3/2/12
The daily ema5 High and Low only display to 12/27/11
The weekly ema5 High and Low only display to 7/9/07

It is odd that there is more than 4 years worth of the weekly data compared to the daily data.

Also when I compare the daily values on the 30 chart with those on the daily chart they are not the same. ie ema(5,high(inv(D))) on the 30 chart is not the same as ema(5,high) on the daily chart. However the ema(5,high(inv(W))) on the 30 chart IS the same as ema(5,high) on the weekly chart.

My timescale on all the charts is dynamic, but I have scrolled to the end of the available data on all the charts.

I cannot see what I am doing wrong.

} 

Also when I compare the daily values on the 30 chart with those on the daily chart they are not the same.

I think it has to do with when eSignal starts the day in a daily interval vs intraday intervals.
A search of the forum will yield various explanations for this. One of those can be found at:

Thanks for your suggestion Wayne. Unfortunately it has not made any difference to the results. My historic interval data is being cut significantly short. Any other ideas??

The issue of the limited historical data is simply due to the reason explained in this thread
If you create a daily and a weekly chart of the same symbol both set to load 300 bars and you run your script on them you will see that the plots will start on the same dates on those charts as on the 30 minute chart set to Dynamic
All you need to do to resolve this is just implement either solution provided at the linked thread
