Are you a good ETF (such as QQQQ) trader?

Question:

I have formulated and automated a trading model (using daily data or higher frequncy data). In backdata tests on some ETFs (daily data), the system generated annual profits ranging from 68% to 213% (no transaction costs or margin taken into account). I trade stocks but not frequent. I was wondering if there is any ETF trader who trades on daily basis and comes up with the better performances.

Answer:
You give no indication of your level of expertise, or if this is some sort of hobby for you.

You know of the problem of "overfitting," of course, where it will not work into the future because of the box you put it in.

You know of the problem of using too little data, too few economic situations, and in general the wrong kind of data.

You know of the problem of your system acting on the close only, while in the real world we must have stops intraday.

There are books written on the many problems and pitfalls of backtesting and system writing; whole books of nothing but problems. But you probably already know this.

Run your system on a simulator real time, or program it to trade by robot at any number of brokerages in a demo account. That will be the true test, and will show you glaring difficulties with your model.

Without knowing more details, it is difficult to comment on anything but the shortfalls of models. The numbers mean very little, except a point of comparison with other models and a beginning of the work in reality.

I have an account but did not tried
