Unfortunately I experience this all the time. Eventually I always find
the setting that I have screwed up and get things back to normal.
There are so many settings (the price we pay for flexibility!) I don't
know where to tell you to start except I can pretty much guarantee
downloading the latest version won't help. However, if you are on a beta
I would upgrade anyway. I'm using 4.70.5, the latest non-beta release.

| Subject: [amibroker] Unusual Backtest Behaviour
|
| Hi,
|
| I have backtested a strategy and recently the results
| were shown to be better by a significant margin, and
| several days later, significantly less in the end
| capital, eventhough ALL parameters and code were the
| same.
|
| Has anyone had such odd behavior from the backtester?
| I have reinstalled my database, and the results have
| gone back to those before the last week or so. I
| can't place the source of the problem other than
| possibly the database corrupting somehow.
|
| In addition, the backtest results indicated that the
| system had undergone a drawdown of -95.88%, while the
| equity curve is clearly positive and healthy for the
| tested period. None of this makes sense, and I'd
| appreciate any suggestions. Possibly, I'll install the
| newest version of AmiBroker.
