Bert,
Using padding has certain implications if your database has data holes.
Specifically padding may introduce "padded" bars that do not really exist
in the price data series. If given bar does not exist then it is NOT shown in the chart.
It is logical, isn't it?
Padding should only be used when it is absolutely needed, i.e.:
- backtesting systems using general market timing (signals based on some broad index)
- creating composites from data that has lots of holes
In all other situations it is recommended NOT to use padding.
Best regards,
Tomasz Janeczko

Subject: [amibroker] PROBLEM WITH BUY AND SELL SIGNALS ON PRICE CHART
> Hello,
>
> Recently, I imported a signal into AmiBroker for BackTesting
> purposes. I ran the signal on a number of indexes and noticed that
> the Buy and Sell signals were listed in both the Exploration and
> BackTest tables, BUT not ALL of the signals showed up on the build-in
> Price Chart. With some investigation, I found that I was missing one
> day of data in the year 2000 for price chart several symbols and it
> so happened that this was the same day that a Buy signal existed from
> the imported signal. As it turned out, by using Pad, both the
> Exploration and BackTest tables displayed Buy and Sell signals after
> this year 2000 date. However, the actual Price chart did NOT display
> any of the Buy or Sell signals from this year 2000 date to present.
>
> I sent notice to AmiBroker Support asking if this changed in a future
> release. I would like the tables and charts to be consistent.
