Online Trading FAQ

FINRA wants investors to make educated decisions about online trading. We want investors to have reasonable expectations about the possible success of their online trading, and to consider the risks as well as the rewards of employing these promising new investing facilities. Here are frequently asked questions about the basics of online trading:

What is online trading?

Generally, online trading refers to buying and selling securities via the Internet or other electronic means such as wireless access, touch-tone telephones, and other new technologies. With online trading, in most cases customers access a brokerage firm's Web Site through their regular Internet Service Provider. Once there, customers may consult information provided on the Web Site and log into their accounts to place orders and monitor account activity.

Aren't online investing and day trading the same thing?

No. Online investing refers to the method of placing orders via the Internet to buy and sell securities as compared to the method of placing orders by speaking directly with a broker by telephone. Day trading refers to a trading strategy where an individual buys and sells the same security in a short period of time (often the same day) in an attempt to profit from small movements in the price of the security.

Can I actually open an account online?

Yes, you can open an account with many brokerage firms online; however, in most instances your account will not be active until the brokerage firm receives and processes a signed application from you. Note that some firms allow for the use of electronic signatures, while others will require a manually (hand written) signed document. Some firms will gather basic information for your account over their Web Sites, then mail you the pre-completed application for you to sign and return. Please make sure to check with your brokerage firm for information on specific guidelines.

Is there still a brokerage firm involved or do I really bypass the broker completely?

All trades involve a brokerage firm even if a stockbroker is not used to help with the trade. Although customers may enter orders for trades via the Internet, customers do not have direct access to the securities markets and therefore must use a brokerage firm in order to execute their trades. Customers should also remember to do their homework where their investments are concerned.

What is the difference between a cash account and a margin account?

VaPar Synth - A Variational Parametric Model for Audio Synthesis
Krishna Subramani, Preeti Rao Alexandre D'Hooge
ICASSP 2020
Paper / Code / Audio Examples / DOI / BibTeX

We present VaPar Synth - a Variational Parametric Synthesizer for instrument note synthesis, which utilizes a conditional variational autoencoder trained on a source-filter inspired parametric representation.

We will be presenting our work virtually at ICASSP 2020! (Presentation Video)

Energy-Weighted Multi-Band Novelty Functions for Onset Detection in Piano Music
Krishna Subramani, Srivatsan Sridhar, Rohit M A, Preeti Rao
National Conference on Communications 2018
Paper / DOI / BibTeX

Propose the use of energy-based weighting of multi-band onset detection functions and the use of a new criterion for adapting the final peak-picking threshold to improve detection of soft onsets in the vicinity of loud notes. Also propose a grouping algorithm to reduce the detection of spurious onsets.

We presented our work at the conference as an oral presentation

Generative Audio Synthesis with a Parametric Model
Krishna Subramani, Alexandre D'Hooge, Preeti Rao
ISMIR 2019 Late Breaking/Demo
Abstract / Audio Examples / BibTeX

Propose a parametric representation for audio corresponding more directly to its musical attributes such as pitch, dynamics and timbre. For more control over generation, we also propose the use of a conditional variational autoencoder which conditions the timbre on pitch.

We presented our work as a poster in the ISMIR 2019 Late Breaking/Demo session

Learning Complex Representations from Spatial Phase Statistics of Natural Scenes
HaDi Maboudi, Krishna Subramani, Hamid Soltanian-Zadeh, Shun-ichi Amari, Hideaki Shimazaki
Submitted to Neural Networks, Under Review
Preprint / bioRxiv / BibTeX

We introduce a generative model for phase in visual systems, and propose a complex domain based maximum likelihood estimation procedure for parameter estimation. We derive analytical gradient expressions for maximum likelihood estimation using Wirtinger Calculus (detailed in our supplementary material)

I presented the initial part of this work as an oral presentation at Honda Research Institute

Research Experience
Variational Parametric Models for Audio Synthesis
Report / Repository / Review of Generative Models for Audio Synthesis

(Ongoing)My Master's thesis work on generative parametric models for audio synthesis.

I presented the work done by me so far as an oral presentation for the first stage defense of my Master's thesis

Compression using Graph Signal Processing
Presentation / Report / Notebook Demonstration of the Code

Inspired by the authors work on compressing distributed data by modeling it as graphs, we decided to try out and extend the idea to a new dataset by performing outlier removal, data imputation and clipping, and were able to successfully compress it at a significantly faster rate(~8x speedup) than conventional techniques.

Data Sonification using Granular Synthesis
Report / Code Repository

Implemented a real-time granular synthesizer on Pure Data. Also ideated a scheme where the parameters of the synth could be controlled externally with data, thus 'sonifying' the data!

Kuramoto Model and Oscillatory Networks
Image Recall

Implemented an image retrieval(memory recall) task using the Kuramoto Model. Extended this to try out graph coloring using Oscillatory Networks.
