Trading Education Thread time 1/8

There are really only two types of trading styles:

1. Mean Reversion Trading
2. Breakout Trading

All other "styles" are merely indicator-based trading systems.

This thread will specifically discuss Breakout Trading

A story of a brave woman who let her "breast" cut to protect the life of Netaji Subhash Chandra Bose!

Neera Arya was born on March 5 1902 in Khekra Nagar, Uttar Pradesh in a distinguished & eminent businessman Seth Chhajumal's family. Since her childhood,

She was a true nationalist & always had a vision of becoming a part of the freedom fighter movement. She was also reportedly accused as an undercover by the British Govt.

That was the time when her father's business was flourishing in Calcutta, though his business was..

3/21
spread across the country but Calcutta was the center of his business and that was one of the reasons why her education was done in Calcutta. During that period of time, she had learned quite a few languages along with Bengali, Hindi, English.

4/21
Her father got her married to a CID Inspector "Shrikant Jairanjan Das" in British India but they were two different individuals, Neera Arya was a true nationalist but her husband was a true British servant. She was highly motivated & she had an urge of getting us freedom..

5/21
so she ended up joining the Jhansi Regiment in Azad Hind Fauz after the marriage. It was the regiment that the British always accused them of spying on British Govt.

It was the time when Neera's husband Jairanjan Das was given the responsibility to spy on Netaji Subhash..

Important paper from Google on large batch optimization. They do impressively careful experiments measuring # iterations needed to achieve target validation error at various batch sizes. The main "surprise" is the lack of surprises. [thread]

The paper is a good example of lots of elements of good experimental design. They validate their metric by showing lots of variants give consistent results. They tune hyperparamters separately for each condition, check that optimum isn't at the endpoints, and measure sensitivity.

They have separate experiments where the hold fixed # iterations and # epochs, which (as they explain) measure very different things. They avoid confounds, such as batch norm's artificial dependence between batch size and regularization strength.

When the experiments are done carefully enough, the results are remarkably consistent between different datasets and architectures. Qualitatively, MNIST behaves just like ImageNet.

Importantly, they don't find any evidence for a "sharp/flat optima" effect whereby better optimization leads to worse final results. They have a good discussion of experimental artifacts/confounds in past papers where such effects were reported.

Remember: Just because an idea is old doesn't mean it's good.

Knowing whether old ideas are more likely to be good requires understanding whether conditions have changed in important ways.

Horse archery was an amazing method of warfare for over a thousand years...then people invented guns, and suddenly this great idea that had stood the test of time became obsolete.

Then again, when underlying conditions don't change much, tried-and-true approaches are probably better.

"Learning the lessons of history" usually just means assuming ergodicity and stationarity in an informal time-series model...

Thiruvizha Mahadeva Kshetram
#Alappuzha 
#Keralatemples 🚩

Thiruvizha Mahadeva Kshetram is located in Cherthala and it is believed that Prathishta of temple was done by Vilwamangalam Swamy. Paramashiva is Swayambhu here and is worshipped as Kalakandha which means who swallowed

Halahala visham to save the world during Samudra mathanam. 

It is a famous temple where people seek the blessings, for curing the Kaivisham. The poison given by someone to destroy a person is made to vomit here. This is removed by making them vomit the poison by a special

medicine.
The medicine for vomiting is made from a plant near temple by Palodathu family. The milk offered to Bhagwan is mixed with the extracts of the plant.

Story says that once this place was a dense forest, and a woman was looking for the presence of a tortoise in the pond

and the tip of her stick hit the bottom and it started bleeding in the pond. 
Frightened, the lady informed every one and after searching in pond people found Swayambhu Lingam inside the pond. Thus Prathishta was done here.

Om Namah Shivaye
