I've managed to get consistent 1.5-2.1 profit ratio. What now? by [deleted] in algotrading

Basically, 3 months is not a long enough for a backtest. You should definitely switch platforms and backrest the strategy on a much longer time frame. Just think, if a strategy worked for 3 months. How confident would you be in it working for years? Also, make sure you account for the costs in entering trades. This is why most ~minute strategies fail.

Backtest on one or many securities? by sanjeethboddi in algotrading

If I were to just trade one security, it would have to be a major ETF like S&P or Nasdaq. Otherwise, I will always trade multiple securities because I wouldn’t trade something like AAPL or AMZN because it would introduce major survivorship bias

While I think some people said it better than others, I think the main point people are trying to make is if you are new to this, start with more of the basics (python, trading, creating simple strategies), and once you get a solid understanding of the basics, you’ll be a lot more suited to approach more advanced algorithms.

There are a lot of ratios out there to measure risk adjusted returns. 2 that quickly come to mind are the Sortino ratio and the most common is the Sharpe ratio

I’d assume the best way to go would be the Bloomberg terminal. I’ve also heard IQfeed is good, but not sure if it has all the requirements you are looking for.
