Is it possible to view indicator plots for in-progress current bar

It appears that indicator plots do not update in the current bar until that bar has completed. For example, on a daily chart I cannot see indicator values for the current day until after the market closes. I can see the price series update on the chart throughout the day. Is there anything I need to change to view intraday indicator values on a daily chart?

Thanks,

No, it's a feature that the Wealth-Lab architect has persistently resisted; probably because the data "in between" bars cannot be used in a script, which processes complete bars only.

I was afraid that might be the answer. I don't understand why it wouldn't be permitted since "in between" bar pricing data is displayed.

Thanks for your response.

For sure all the ticks are received because after loading the history, WLP builds the new bars from the ticks. The issue underlying all of this is that in order to render the chart, WLP must execute the script, and when the script is executed, it trades and alerts. It's not an unsolvable problem and the "hooks" are actually there to do the job of recalculating indicators with partial data. I could be wrong, but it's probably just a matter of priorities to finish the job... and for now there are bigger fish to fry.

I am a swing trader who has used Metastock for years. I am dismayed that I can't use daily data to trade with as the current day isn't presented. If I sign on to streaming data I can get a data point but it doesn't update with the stream. I can't swing trade with out applying my charts to the data near the end of the day. What can I do to implement a useful system. Aslo I'm not a programmer as I haven't programmed since the 6os.

Eugene; Thanks for the info. I want to be looking at a chart that is updating with today's tick data or at least every few seconds. Then while evaluating some live charts I will make a trading decision. This is the way I've traded profitably with Metastock. The intraday 1 minute charts seem to be 20 minutes behind the market and they don't update either.
Does this mean that wealth-lab just isn't intended to be a real time chart tool?

This may mean that you're running a trial version of Wealth-Lab Pro where Fidelity streaming data is not available (have to open an eligible account for the features like Fidelity streaming/fundamental data and automatic order placement to appear).

Is there a way around the missing last bar and indicators other than going to a shorter time frame?

The last bar and indicators are not "missing", they are incomplete and for this reason not yet available. Indicators updating on the partial bar are somewhat impractical because of Wealth-Lab's modus operandi:

FAQ > Is it necessary to have access to intra-bar tick data to daytrade with Wealth-Lab?

Some techniques can be used as a workaround, for example:

1. Use a provider that returns partial daily bar such as Yahoo! Finance (enable "Always return data with partial bar" in Data Manager > Yahoo tab).
2. Use a technique from our Knowledge Base:

Accessing Intraday data from Daily
Updating a Daily indicator using Intraday values

Note: if you get indicator updating on the partial bar by using any of these approaches, its reading could change later to the extent of invalidating an already triggered signal.
