I thought of the following strategy:
- Choose some good ETF (doesn't really matter how I choose it for my question) - let's call it
E
. - While price of
E
is higher than 90% of its peak historical price (example: if peak is 100$ so enter this loop if price > 90$)
2.1. Wait - Buy
n
units ofE
(now the price <= 90% of the peak). Let's mark the buy price atp
. - While price of
E
< (1.05 *p
)
4.1. Wait - Sell
E
(now we have at least 5% profit). - Return to 2
I tried to look at some sites for backtesting it, but didn't find how.
Do you know any place where I can backtest this strategy?
