Until a computer can write a new program from scratch to solve a a hard and real problem about the world that it has conceived and that will work, all this talk is something more than speculative. I don't want to call it stupid but it may be.

All over the range since returns only count.

This is worth looking at since it is free for two months. I have tried the code for Quantopian and it works well after changing the sid parameter to proper one in the two lines context.security = sid(8554) and context.xtl = sid(8554) Download page

Be careful using data from Google and other sources. Check for missing entries. Google misses dates over entire database.

Several traders I know make money with automated system, some make a good living and a couple have made it big. You need verifiable records to determine is this is possible. Here is a tweet from one of those I follow with an example from Quantopian contest. More than 22% in less than a year...

If you want to make very large gains, you must be prepared for very large losses as these two go together. Then odds are high that you will lose everything before reaching target due to exposure. Luck factor increases with target. If you want to grow $1000 to $1500, required luck is say 10% and...

These sound to me equivalent in theory but human has limited capacity in processing numbers so must go quantitative. I heard there is a 3 1/2 year old in Russia playing chess with pros but mind you this is outlier and less than 0.1% of traders will be able to beat the machines (pros) as with...

Sure, I'll try. Decay and higher probability of market changing as time passes. Then there is the problem of data-snooping bias. If you forward test a few strategies you may think one matches your backtests by luck. There is an expert in this area that recently wrote an article in Medium. In the...

Bitcoin architecture has reached certain limits. Many articles about this in last few days. Transactions take several days to confirm and fees increased. But bitcoin speculation and frenzy along with high volatility should not be viewed as unique to this cryptocurrency.An article shows some...

HFT is the market maker in these new markets. Insider trading hurts all but destabilizing market makers increases the damage.

NT7 is an excellent product. We use is to test some of our strategies and compare results with other platforms. Is anyone familiar with the NT7 code generation of DLPAL software? How difficult would it be to convert it to NT8? Or in general, what does the conversion effort involve? Learning a...

It depends what you day trade, how much you pay in commission versus spread and whether you use a proven method. This is not an area for too much experimentation. Either you have a low cost working setup or not.

This Amibroker developer is a genius, I know. He probably figured out a way to make the data requests look like they come from a browser, not an API. But Yahoo can terminate that too anytime. If Amiquote can work with Kinetic it would be great, NinjaTrader and Amibroker can benefit from this...

With the format you have your chart data is mostly useful to your software users. If you or kinetic can offer an API for easy download in various formats for use with analytics (Python, R, etc.) you can attract a large customer base fleeing Yahoo but you must act fast. There are some programming...

I wonder is this is related to recent letters by exchanges to data vendors about charging thousands per API use. This was discussed somewhere. I was told by someone that after a few smart traders discovered how to defeat HFT they lobbied to exchanges and asked them to stop providing data via...

Exactly!

Forward test is waste of time because system has higher probability to work in near term and fail afterwards.

Result of artificial scarcity. Rapper will issue only one album. Dot com signs. Exercise caution.

Ha... everyone went to Quantopian looking for crumbs. They claim > 100K subscribers.

If it looks like a solicitation it is illegal.
