I have several charts with a number of parameters. Occasionally these
parameters reset to default values. Does anybody know why this happens? I am
using AB 5.29.6. TIA
Okay, will switch.

the script think its on when evaluating statements for a given trade? trade
entrybar? exitbar? neither?

You are right; i was actually able to run multiple instances of AB connected to
different databases but both being fed by a single IQFeed client. It takes away
the problem of running multiple scans for now (for multiple systems; and
luckyly i dont have to mix all the systems into one big file) a
Yup, always pays to check the release notes too ;) I've been caught by that a
few times myself.

Yes.
Once you enter the custom backtesting phase, the active symbol is ~~~Equity.
Any arrays constructed for symbols during the signal generation phase are no
longer accessible.

Hello,
You should NOT do that that way (keying with barindex()) that is
complete overkill.
AmiBroker supports ARRAY static variables, just use latest version 5.29.6
and use the formula I gave earlier.

Thank you. I have been freezing up my machine for 30 minutes at a time trying
to get the staticvarset() to work (never did). This does it. Thanks again.
For my edification, could you tell me why the alternative below doesn't work?
Is it that once the backtester begins, all arrays (
If you've ever made a backup copy of the entire AmiBroker directory (e.g. as
per guidelines when upgrading to the latest beta), you could probably dig it up
from there.

For what it's worth, static arrays were introduced to the 32 bit version

I distribute quite a few charts to friends and would like to fix them at a

If you don't find a simpler way, this could certainly be implemented using low
level custom backtester API.

Hi,
While working on my watch list, with the intention to remove one of the stock
from my watch list, I accidentally click "Erase Favourites". Then, my favourite
list was erased completely. I don't see an "undo" option to get my favorites
back.
How could AmiBroker let this happen? I spent so m
Thanks Tomasz. One stupid follow up question: my understanding is that
StaticVarSet will take only a single number not an array, therefore do i need
to create a loop outside the CBT from 0 to BarCount - 1 and create a static

Hello,
Foreign is costly. Move your calculations OUTSIDE custom backtest part.
ATR can easily be calculated outside CBT and passed via Static variable.
So instead of Foreign use Static variables. Store your ATR into static
variables keyed with
StaticVarSet("MyAtr"+Name(), ATR(14) );
and insi

I have run into some major performance problems when trying to add a single

sma1 = MA(P, movavgperiod);
sma2 = MA(sma1,smoothing);

Dear friends

Throw a dart. Just about any broker will fall head over heels to have you
trade any stock in the S&P500 index. Be sure to investigate commissions for
the size that you trade and service/support issues as these will differ between
brokers. For example, one commission schedule might be attracti
Hi,
if my system is flat I would like to have a stock in the Equity instead of the
linear line that comes from e.g. 2% interest.
Does anyone know how I could tell Amibroker for the case that the system is
flat to take an ETF (e.g. TLT) as the equity?
I need an extension for e.g. this system:

Is it possible to set up backtester to start calculating the formula at

Backtester seems to always start at midnight.
