Training mode.
<SPAN
class=606461512-26072004>I've asked for something similar myself, maybe with a
slider or something to control the number of bars blanked at the end, rather
than only stepping through one at a time. Besides training your mind, it's
also useful for evaluating the behavior of indicators that "guess" about the
future, or for other reasons change shape as more data becomes
available.
<SPAN

<SPAN
class=606461512-26072004>The closest I know of that you can do currently is to
set all prices after a certain bar to null. Some types of indicators do odd
things right at the transition point, so you may need to null them out too.
For that reason, you may have to recode this arrangement specifically for
every pane, not idea;.
<SPAN
class=606461512-26072004>
<SPAN
class=606461512-26072004>It also won't remove hand-drawn studies, much less
put them back later. You might be able to code up something that sets the
color of studies to your background color, maybe?
<SPAN
class=606461512-26072004>
<SPAN
class=606461512-26072004>It's better than nothing, and AFIK, the best we can
do without it being built into AB, but I too hope Tomasz adds a feature like
this.

<BLOCKQUOTE
>I
would like to set AB's data to a selected date back in time, clear of
all existing studies I might have drawn like trendlines ect, but
trendlines and other studies are able to be drawn. Then every time the
space bar is pressed a new days(weeks or tick) worth of data is
added.The reason for this of cause is to test or practice trading
like backtesting your idears and instinks in real time. Is
there currently a way to do this?Downloading each days history is
not a solution. To time consuming.Any idear?Thanks
