i cant remember where i got this but have used it in the past to check profitability of the system that im using
There are times I'm wondering if you're just joking around or if you're actually serious. Market replay have been around forever on most new platforms. You can also back-check/test manually bar by bar on historical n-minute/second charts. If you really want to there's nothing to prevent you from doing all kinds of back-testing/checking of data. I deliberately write 'checking', because back-testing is often associated with a mechanical approach/strategy. In contrast, you can review historical prices within whatever approach you're utilizing. I don't think that would work out. If you're trading the larger swings intraday you would not have executed 10 trades in 20 minutes. Obviously. Personally, my target is the day range (high to low or vice versa). And that may take as long as 6 1/2 hours to form. Some days I'll even enter during the Asia Open and hold until the electronic close 23 hours later. In a perfect world I'd do one trade per day from high to low or the opposite. My best trade last year had a duration of 18 hours for a profit of 100 points on ES. Total profit that day was 120 points from two trades. Win rate 100 % on that day. Long term it seems to settle well below 50 %, though.
Hello Drawdown Addict, What does Github repo mean? I used NinjaTrader to program and back test trading ideas.
I am serious, mostly. I only know how to download data from Yahoo Finance to backtest. Didn't know I could store real time data for later usage... I don't trust or want to pay for any data because I agreed with @SimpleMeLike that with millions of smart people mining those, there would be no good methods left for me. I can only write simple VBA codes on excel and it took me months to write my last one. To save time I mostly reduced problems to simple first order relationships, so I could calculate them by hand.... Good thing once you understand the first order relationships, there are a lot you can do without fancy codes, e.g. outcome vs win rate, the red line @toucan showed.
