Redis only NOSQL database growing this year

 

Redis only database growing this year

This was from a member so thanks to them

There are no major changes but it’s worth mentioning that Redis has gathered more points this year than it did in 2016 (34 percent last year and 43.2 percent in 2017) while MongoDB experienced the opposite change: it lost some points in the meantime (60 percent in 2016 and 49.8 percent this year).

Who knew there was a Bloomberg distributed open database

There are other neat projects from Bloomberg as well

By the way, Redis still better with Lua embedding scripting

How to Build a historical database with Google or Yahoo Finance

Forget these old school databases. Times have changed since these with legacy data feed sources as well. I just focus on Redis NOSQL which answers a lot of my current data repository problems.

Here is the old story of what was posted:

Here is my latest Redis searches on the blog of the latest interesting info you should know about:

Redis 4 NOSQL database of choice for machine learning and graph objects

More Algo Trading database and charting queries

Continuing series of queries from the same member

Hi Bryan.

 

On your journey to build your trading system, you mentioned that you were going to use Redis 4 NOSQL.

But you also mentioned MongoDB, which I was watching another video from that european company that uses MongoDB.

 

Question:

Are you using Redis 4 because you are migrating to a Mac OS GUI environment because Mongo is for Linux or can Mongo also be used for Mac? I would assume that it doesn’t matter.
Is Redis 4 just better, faster than MongoDB, etc? Is cost part of your reasoning, etc?
I am leaning towards going the Mac direction as well and using Linux for the back end.

 

Keep in mind, I am serious about getting deeper into coding (a few people I know have done coding or are in IT careers that could and would assist me).
I’ve been using PC’s for the last 15 years mostly but no3

 

My sister, who used to build PCs installed Ubuntu on one of my PCs as a backup for my data in case I couldn’t access files through Windows.
I am side-tracking a bit I realize, but I thought context is important so that you realize I am not a total newbie with OS environments.

 

In one of your videos, you mentioned charting you were going to do on Mac, called “Colorec” … maybe I didn’t hear properly.
I did a search on it, and could not find anything or that other application I thought you said called “Telerec”… You spoke a bit quickly, so I rewound the video but couldn’t make it out.

 

You mentioned other charting applications like Chart Director and Gnunplot? Are those for Linux or PCs?

 

I answer in my usual video style here

From kdb+ to monetDB open source fast database

From kdb+ to monetDB open source fast database

After seeing job posts, this article lead me to this database choice:

We’ve created a roundup of the top column-oriented database systems: http://www.timestored.com/time-series-data/column-oriented-databases

This includes kdb+ and some open source alternatives.

We have done some initial work at benchmarking common time-series queries and found open source monetDB to be particularly fast…we will hopefully be able to publish some of those results at a later date.

http://quant.stackexchange.com/questions/3156/is-there-any-thing-out-there-as-a-substitute-for-kdb

 

So that lead me to MonetDB (same as kdb+ which is an in memory column store)

http://www.timestored.com/time-series-data/column-oriented-databases

http://dev.monetdb.org/hg/MonetDB/graph/

This is also compatible with FreeBSD

vs my fave Redis NOSQL but these are completely different animals

How to Build a historical database with Yahoo Finance

How to Build a historical database with Google or Yahoo Finance

For some reason I got an old post from two years ago that suddenly people were reading. It is currently about how to build out a historical trading database with Yahoo finance as your source. This is somewhat very limiting to implement. However, I have even a better solution which is part of my video described below.

 

If you want to read about a potential way to build out a historical trading base at nost cost, read this

Demo of automated trading Positions management Python Script

 

As said earlier, I have a new video that demonstrates how to automatically manage your trading positions with various ways of calculating your market exits. There are numerous metrics that you can use including the ones that I demonstrate. There’s a simple chart generated for the trading automated stop losses as well as interaction with my NoSQL MongoDB database.

 

Check it out all here

 

Also, don’t forget I have a detailed source code walk-through on the script which is my longest one yet for this new upcoming automated trading system. All my Quant Elite members can get access to the source code as well as his video by going here.

 

I would say I am about 75% done for Phase 1 of this automated trading system course series. I’ll also be working out an itinerary later in the week. Due to time constraints that I have over the next while, I will be only most likely doing this a “one time” LIVE event. It will be recorded for those that do miss it but considering the value that you will receive, it is the most affordable that you will not get anywhere else online. As a result, I would highly encourage you to get my Quant Elite membership now!
