What that says to me is that you will never start your algo, because you are afraid you will start at the one time in the life of the backtest where it will fail. Take it from me. With the markets being as down as they are, and assuming you are a long-biased algo? The time to start with real money is NOW.
Surprising new book suggests profitable rules-based strategies are plentiful. But you have to top up your trading accounts numerous times. Happy reading & good luck!
200 day crossover is Something I have looked at many times over the years, as a tool. And haven’t figured out how to avoid the whipsaw. Maybe set a limit of crossover +/- 2%, and/or stays there for 3 days? Or something like that. Haven’t back tested it. Plus I don’t have patience required. But that’s a whole ‘ other thread.
While some of the strategies in the book had limited data, most of the combinations of chart indicators and candle patterns produced positive results. It's worth noting that the author included links to the codes used, which is a great resource for traders. Thanks for sharing.
