This is a simple trading strategy that provides some core mean-reverting properties. It involves the following:. The average in this case, is calculated by a linear regression curve because a simple moving average is often a lagging indicator and becomes a big problem with long look-back periods.

Playing around with the look-back period can provide some interesting results, try it out! Thoughts and suggestions are always welcome. More on the strategy can be found here.

Can you rewrite this so we can backtest it against individual stocks rather than the whole market that would be appreciated! I also fixed where the lower bollinger band was missing.

Doesn't this function run every minuet in a full backtest? Wouldn't that cause the check to happen every 20min as opposed to 20 days? Thanks for mentioning that, I hadn't thought about how it would work in minutely data as I only tested it in daily data, but here's a way to test it in minutely data as well. I'm unaccustomed to reading Python code, so I may be missing something, but where is the "exit position" command in your code?

I see you buying shares when you're below the lower threshold and selling when you're above the upper, but I don't see you exiting anywhere in the middle. I ask because, in the header, you say that positions are exited when the price crosses the moving average. Again, new to Python, so I could be very wrong.

Unlike the futures market, the long side of stock markets work quite differently than the short side, at least that is what I have seen. It is probably because we humans react differently to greed and to fear. The short sides are quick steep drops lasting for short periods, while the long side is more gradual climbs and lasts longer. Based on bollinger band mean reversion strategy, the mean reversions need different parameters to work on both short and long sides.

I love to see the exchange of ideas how to make money with youtube monetization generosity of the able coders here. To my knowledge, linregress 1 returns the intercept of the linregress line while [0] would return the slopemore here And you're right about the exit position, there is none for now, will get on promag archangel ruger 10 22 tactical stock kit soon.

And yes, there is a bit of leverage used here although as to how much would depend on the order amount. Ah yes, you're right about linregress. From a statistical point of view, that is a very strange choice on their part.

Are you able to run the strategy without any leverage, so we could get an idea of what the returns would be in that situation. I ask because I've played with similar strategies that gave nowhere near put call parity foreign exchange same performance as yours, but they've been unleveraged, so I want to make sure I'm making a fair comparison.

Still working on the leverage, but I've incorporated exit positions into the algorithm and the returns are very different. If you'd like to find out more about leverage there's a Quantopian thread here as well. The current exit position is whenever the price crosses the mean, and I think there'd be a better exit tradestation metastock data than that especially with earn to die 2016 hacked unlimited money and boost 20 day lookback period on that.

If you have any suggestions on that, please feel free to post.

The latest backtest I've uploaded doesn't use leverage so you could use that as a good way to compare your tests to mine. Here's a way to adapt it to minutely data which works! Marco, sorry newbie here It seems closer to https: Did you post in the wrong thread? Can you outline any new changes you made When I cloned and run your algorithm, I got the following warning I created this algorithm before 'history ' was released.

The last version that I have here uses history to query for past data, feel free to use this one instead. Hi Seong, Well I feel that if rather than buying when close price crosses lower Bollinger for the first time, you should buy it once close price resurfaces and equals the lower Bollinger and similarly for shorting also. Have you ever heard of overfitting? Walk-forward testing among other things are needed! Can anyone help me change this algo to something smaller?

What's up with that? BTW I'm a total noob. The problem here is probably related to your order, being way too large. What's happening is that you are buying and selling lots of shares which makes your strategy unreasonable. For a good ressource on order types, try:. Sorry, something went wrong.
