It is intended for users who have basic programming knowledge of Python and want to start with NLP. Topics covered in this video include: Setting up the Environment.
After providing an overview to this video series, this clip shows you how to install and run Python, as well as Anaconda and the necessary libraries including NLTK. Exposure to programming concepts is required to interpret the codes covered in the course. However, experience with Python coding knowledge is optional. If you want to be able to code and implement the strategies in Python, you should be able to work with 'Pandas Data frames'.
All the required skill sets are covered in the foundation courses available in the learning track. Quantra is a marvelous source for Alpha strategies and a powerhouse of great instructors with market experience. Also, Quantra gives a clear research path so that one can research his own Alphas. I recommend it to traders and researchers.
You will gain access to the entire course content including videos and strategies, as soon as you complete the payment and successfully enroll in the course. Yes, you will be awarded with a certification from QuantInsti after successfully completing the online learning units.
No, there are no live or classroom sessions in the course. You can ask your queries on community and get responses from fellow learners and faculty members.
Fast-speed internet connection and a browser application are required for this course. For best experience, use Chrome. There is no admission criterion. You are recommended to go through the prerequisites section and be aware of skill sets gained and required to learn most from the course. We respect your time, and hence, we offer concise but effective short-term courses created under professional guidance.
We try to offer the most value within the shortest time. There are a few courses on Quantra which are free of cost. Please check the price of the course before enrolling in it. Once a purchase is made, we offer complete course content. For paid courses, we follow a 'no refund' policy.
Some of the course material is downloadable such as Python notebooks with strategy codes. We also guide you how to use these codes on your own system to practice further. We focus on teaching these quantitative and machine learning techniques and how learners can use them for developing their own strategies. You may or may not be able to directly use them in your own system. Quantra environment is a zero-installation solution to get beginners to start off with coding in Python.
While learning you won't have to download or install anything! However, if you wish to later implement the learning on your system, you can definitely do that. All the notebooks in the Quantra portal are available for download at the end of each course and they can be run in the local system just the same as they run in the portal.
We encourage you to implement different concepts learnt from different learning tracks into your trading strategy to make it more suited to the real-world scenario. We provide you guidance on how to make a profitable strategy using different techniques and indicators, but no strategy is plug and play. A lot of effort is required to backtest any strategy, after which we fine-tune the strategy parameters and see the performance on paper trading before we finally implement the live execution of trades.
Natural Language Processing NLP is a branch of artificial intelligence that is focused on the interactions between human language and computers. The objective of the NLP is to read, understand and derive meaning from the human language. One of the applications of NLP is sentiment analysis.
Sometimes organisations want to know what customers are saying about their products or services. NLP extracts information from sources like social media and performs sentiment analysis on the data. It provides a lot of information about customer choices and their sentiment towards the products or services.
There are various applications of natural language processing NLP. Sentiment analysis is one of the widely used applications of NLP. The goal of sentiment analysis is to identify sentiment from the text. This can be further extended to making trading decisions. Other areas where NLP is associated are machine translation, automatic summarization, text classification, question answering etc. Refer to Section 2 of Natural Language Processing in Trading course.
You can learn about natural language processing NLP and its application in the Natural Language Processing in Trading course. In the course, you learn to do sentiment analysis on the news headline data and predict stock and bond prices. You also learn about various embedding methods such as Bag of Words, TF-IDF, Word2Vec and BERT. Along with NLP techniques, you learn to use a machine learning algorithm to generate sentiment from news headlines.
Word embedding is a technique or model to map reinfor sentences or a group of words to a vector of numerical values. These vectors can be fed as input to the machine learning algorithm.
This can further be used for sentiment analysis, translations, and other applications. There are different word embedding methods such as Bag of Words, TF-IDF, Word2Vec, and BERT. You can learn about these word embedding techniques and their applications in the Natural Language Processing in Trading course. There are various Python APIs such as Webhose, NewsAPI, GoogleNews which aggregate news headlines from different media sources.
We have used Webhose API in our course for the illustration purpose, which provides access or free trial for ten days. Also, for various other sources API requests are limited to a certain number of requests per day or month. Once the limit is reached, one needs to purchase the API access for further use. We used free data sources for news headlines data in this course. You can also access free news headlines data from various Python APIs such as Webhose, NewsAPI, GoogleNews.
However, these resources have API requests limit per day or month. Natural Language Processing in Trading. If you are looking to trade based on the sentiments and opinions expressed in the news headline through cutting edge natural language processing techniques, this is the right course for you.

There are different problems associated with these two data sets. Unstructured data like Twitter feeds consist of many non-textual data, such as hashtags and mentions. For structured data, the size of the text can easily cloud its essence.
To solve this, you need to break the text down into individual sentences or apply techniques such as tf-idf to estimate the importance of words. Converting the text data to a numerical score is a challenging task. For unstructured text, you can use pre-existing packages such as VADER to estimate the sentiment of the news. If the text is a blog or an article then you can try breaking it down for VADER to make sense of it. So, you will have to create a library of your own.
When building such a library of relevant structured data, care should be taken to consider texts from similar sources and the corresponding market reactions to this text data.
To understand the score of the sentiment of such text, you need to develop a word-to vector model or a decision tree model using the tf-idf array. Visit QuantInsti website to learn how to generate and backtest the trading model.

They stressed the importance of open source and standards, noting that they were working through FINOS , the Fintech Open Source Standards organization, which was spun out of Symphony. How can word2vec help? What is word embedding? This core observation — that domain adaptation is important — is the centre of the second sentiment model, where, instead of counting words from a general-purpose dictionary, finance-specific words from the LM dictionaries are counted.
