Hey Kris,
I've used a variety of backtesters now and they are essentially
worthless to most traders, in my opinion. If you can visually see an
indicator working well, that it generally indicates a good buy/cover
or short/sell signal, you'll be okay.
It's far more productive to focus your time on creating a variety of
scans and explorations that run automatically throughout the trading
day, or at EOD. Look for setups way in advance, and then patiently
wait for a buy or short trigger so you can pounce on them at the
perfect moment.
What backtesters don't ultimately give you is confidence in trading,
I find. I've gotten excellent results in backtesting only to find I
did not trust the system and couldn't trade it.
Now, if you are setting up an automated logical order system that has
nothing to do with human emotions, then by all means use backtesting
to the fullest.
If you do test, there's only really a handful of indicators that are
worth testing anyway, IMO -- try T3, IFT-RSI, Relative Slope
Trendlines, and Finite Volume Elements, as your main indicators, and
you're good to go. MACD and stochastics are good ones, too. Most
important, don't forget to use a price trendline indicator to verify
your signals are happening at the right time.
That's my experience, anyway. I feel I wasted a **lot** of precious
time diddling around with backtesters.
Best wishes and good luck,
~Bman
