Here's a thread compiling the things I wish I knew before starting CP.

RANI GAIDINLIU:THE LESSER KNOWN FREEDOM FIGHTER

Rani Gaidinliu joined the freedom struggle at 13 &was sentenced to life imprisonment at 16."We r free people—the White should not rule over us.”Thus calling out to her Zeliangrong tribesmen was the voice of 13yr-old Rani Gaidinliu.

She joined the freedom struggle in the present-day Northeast India. Today, her struggle is lost in history as most of her countrymen wouldn’t even have heard her name. B'coz our history textbooks tell us that only Mahatma Gandhi &Pandit Nehru got India its Independence.

At 16 yrs of age, this valiant girl was sentenced to life imprisonment for leading a movement to drive out the colonial rulers from Manipur and Nagaland. Nevertheless, she was released in 1947 after India’s independence and was given the title ,"Rani of Nagas".

EARLY LIFE AND HERAKA MOVEMENT

Gaidinliu belonged to the Rongmei clan of the Zeliangrong tribe in the Tamenglong district of western Manipur. Born on January 26, 1915, she was fifth among eight children.

Her native village was Nungkao, which is present day Tamenglong distt. Brought up in a specially backward region,she couldn't receive any formal education. However,this didn't stop her from joining the freedom struggle. At the age of 10 she came under the influence of her cousin.

1. #Qanon told us that Saudi Arabia is a central piece of the puzzle in taking out the Deep State...we are watching the Deep State attempt to remove Crown Prince MBS and disrupt Pres Trump's administration's ties with MBS and the "new" Saudi/US coalition. Early in his admin,

2....@Potus sent Jared Kushner (JK) to SA on an undisclosed trip and told King Salman that business as usual was over, and if he wanted Pres Trump's support, Prince Alwaleed would have to be divested of $ and power; Alwaleed is one of top Deep State $ men and was tied to HRC.

3. @Potus knew that before he could begin cleansing the US and the rest of the world of the DS, he would have to cut one of the financial head's off the snake (Alwaleed). After JK met w/ King Salman, Alwaleed was arrested and divested of billions; MBS became leader of SA.

4. SA loves Pres Trump because he's a man of his word; SA could not trust Hussein or Clintons because they use SA for oil and leverage; SA has many factions, but essentially you have the new and upcoming SA that is attempting to modernize through Crown Prince MBS, and then you

5...have the old guard represented by Alwaleed who was one of the Deep State financial heads and loyal to the DS more than SA; SA knew Hussein was financing Iran to hold western world hostage, and SA was caught in middle of Deep State black mail; this is why @Potus was celebrated

Read this. U may get it for free.
Short straddle :
What is ?? Sell an atm call and put.
Instrument: mostly bnf and nf.
Now there are versions of it.
1. Best version :
Enter around 9.15-20 and exit around 3.20. No adjustment nothing.
1/n.

If u r doing it on zero leverage(meaning u have full capital of around bnf's notional contract,i.e. 40000*25 = 10lacs), then u r most likely going to make better than fd or anything like that.
Simple rules : friday,monday, tuesday do for weekly. Wednesday and thrusday next week

So, gamma moves can't impact much.
Another better version of mahesh chander kaushik is to do it for monthly expiry.
Bigger premiums and never hav to worry about 200-300 points sudden moves.
2. 2nd version : have combined stoploss of premiums and re-entry criteria. Example :

Let say 40000 straddle is at 600. Sell at 600 and hav combined sl at 650. Many algos are providing this. U can even place stoploss in % terms. Like, if sold straddle at 400 and placed 10% sl, means if 440 combined premium touch, it will be stoploss.
Let say, in morning,

U sold straddle at 600 and it sl hit at 650. Now, u placed reentry at 600 with same sl. This time may be linear decay happens and u may cover morning's loss and make some profit.
3rd version : stoplosses at each leg and trail sl to cost type.
Example , 40000 straddle at 400.
