daniel,
if you are still around. i would very much value your evaluation on
the latest version of Amibroker or any other software.
currently i have used WLD, NeoTicker and to lesser degree, AmiBroker.
WLD i am most familiar with, but with fidelity taking over..time to
move on. NeoTicker is very powerful, but support and user community
is very lacking.
that leaves AmiBroker, which i am hoping you can give an update on...

Please don't flame me, as this is based on my perceptions, and yours
will probably differ. :)

few things that would make it superb. Being able to plot a triangle
or box would allow one to plot Gartley's or highlight trades with a
green or red box based on whether they made a profit or not, or
maybe highlight the opening range in orange until it is over.
Changing background colors would allow gradients to show a condition
getting better or worse. You get the idea...
> - No position management functions. I find it harder to program
systems when you rely on a simple boolean on/off for entry/exit
signals. In WL, once a position is created, you can use position-
based functions like PositionEntryBar() or PositionActive() or
PositionMFE() to loop through a collection of positions and apply
simple tests/exits to them. Multiple concurrent position systems
are greatly simplified this way as trade management is done on a
trade by trade basis. FWIW, this would eliminate the need for
functions like ExRem().

so it's not that big a deal. But for complex scripts (ie a native
AFL genetic algorithm implementation via includes) this would be a
life-saver.

reason I have WL.
> - Position Sizing algorithms needs to be done via your script. WL
allows you to separate the Positions Sizing from the trade
entry/exit scripts. This makes it easy to try various position
sizing algorithms without the need to change any code.

was implemented really well because of the attached portfolio, and I
have used it with over 20 positions auto-trading at once on a 5 min
timeframe. It didn't miss a beat.

etc) via a menu option. This is a great *built-in* repository for
those starting out, or for those looking to explore other ideas.
Simply refresh the system by choosing "download chartscripts" from
the menu.
> - Position Sizing is a separate script. Once you see the
difference that position sizing can have on a strategy, this feature
becomes critical. You can apply any sizing strategy during system
ranking/optimization/portfolio simulations/etc. This can
dramatically change the results of these methods.

So every system test you run has to re-parse the data, which can
slow you down dramatically on large datasets.
> - Simple/Rapid indicator and system development is slower compared
to AB. The Metastock-style array notation in AB is a huge
timesaver. There are wizards in WL3 to help with this, but I still
find the process cumbersome compared to AB/MS.

been nice to trade the ES or NQ on tick bars, but it can't be done
yet.

I need to rapidly test an idea, or if I am trying to run a test on a
large set of data. I then move to WL to refine the ideas, apply
position sizing, and then deploy them via the auto-trading. So for
me at least, the two complement each other very well.

stress that both packages have there place, and although AB is great
in it's current state, there is always room for improvement. Or
else TJ would have retired ages ago, right TJ? ;)
