Tomasz:
Have to disagree to some extent. As you note,
the interface is a matter of personal preference, although I tend to side with
Bernard. However, and most importantly, from a "programming dummy" user's
viewpoint, WealthScript might suffer from the problems that you note, but it is
relatively clear with respect to trading system and drawing
functions. Perhaps it is not as efficient as AFL, but it is easy to build
a system with commands like BuyAtStop, GetDate, CumUp, etc., with only a
couple of tutorials as a guideline. And being able to incorporate drawing
functions (e.g., DrawLine, SetBarColor, etc.) in a straightforward manner is
great, although more is needed in this area (to be expanded in version 2
according to WL). Definitely an attempt to produce a user-friendly
programming environment. Easy to use, "intuitive" system and drawing
functions are arguably essential endpoints. So much the better, if
these attributes can be further enhanced with respect to speed and simplicity,
and placed within the AmiBroker setting. Or so it seems to this
programming dummy.

Dear Bernard,
Thank you for your opinion.
I have downloaded a trial version of WealthLab
desktop and had a look at it.
Frankly speaking I don't like its user interface
- but this is my private opinion.
What I like are extensive back-testing
statistics. These I would like to see
in AmiBroker.
As for the WealthScript I find it quite
complicated. You have to have at least
3-4 times more code than in AFL to do the same
thing.
Also - I tried to check very basicMA
crossover system and wanted to simulate
trading using 100% capital and WealthLab
displayed very strange equity curve
(with negative cash amounts). What's more
WealthScript seems to be very slow.
As for optimization: yes I will include
optimization in 3.7, this will include
multiple-security optimization.
By the way: it seems that you can only optimize
for one stock in WealthLab, is it true?
Anyway, some ideas are worth
implementing.

Dear Tomasz
I have a doubt if my message was
published since I can't see it and in fact I haven't finished it. So here it
is completed.
Well I like the following feature (in the
desktop version):
-A window where you can easily find the
systems/commentary classified in folders and sorted by name or date
etc.
-The ChartScript window, the equivalent of the
AB main window, have some TAB where you can very easily evaluate a TS :The
first one show the performance, the second the list of the trades, thenone
for the alerts, one for the text of the TS, one for optimisation (I hope
that you will implement it in AB soon), an other one called MonteCarlo (I
guess it is to make more complex optimisation using the Monte Carlo method),
the last one is called Analysis Var but I don't know what it
is.
They have also a window where you can
select the trading systems, run them on a watchlist and perform a
ranking of the performances..
You can download the desktop version for a free
trial period and have a good idea of the product.
It is much more expensive than AB but you have
given to us the proof that you can easily compete with such
products.
In fact more I try to find a good trading
systerm more I came to the conclusion that there is not one good trading
system but we have to find for each period of time, for each
market and perhaps for each stock one good TS which could have to be changed
and adapted as soon as the market conditions move.
This means that we need to have a toolthat
allow us to optimize and compare a bunch of TS periodically.
So I whish that AB could help us in this task
and allow to adapt and optimise our TS easily.
For this Tomasz it would be nice if wecould
more easily change the parameters of the TS or the charts with contextual
menus intead of having to write AFL codes.

Hello Tomasz
Yes, there is some good ideas to use in
terms of agronomy (windows design and parameters settings).

How about entry to lowest trough = trade
drawdown
Did you notice the script functionslisted
on the Wealth-Lab site? Is that where AB is
headed?

Hello,
Thank you for the
information.
BTW, here is a definition of Max.
Intraday drawdown from wealthlab:
"Max IntraDay Drawdown
This value represents the greatest peak to trough
distance in your equity curve. Beware of Systems that have a
high Drawdown value."
This is exactly what I meant in my previous
e-mail: "greatest peak to trough distance".
Now: how should we call entry to lowest trough
distance ( a drawdown measure already present in AmiBroker)
??

Tomasz:
Since you will have maximum drawdown,
I suggest including Risk-Adjusted Return (RAR). This is a
standard system evaluation metric that divides a risk
measurement by the annualized rate of return. You could
use maximum drawdown as the risk measurement, but other measures
(volatility, standard deviation, etc.) would also
work.
The following link lists the system
evaluation parameters used by Wealth-Lab:

are:- Annual system percentage profit- Annual
B&H percentage profit- Maximum drawback calculated
from maximum equity value to the minimum equity
value (BTW: How to name this one? I have no
idea) (note this is different from current max.
drawback calculation which computesmax.
equity dip from the trade entry)- Bars out of
marketI have got already some of your earlier
suggestionsbut anyone has something more?Best
