My very initial thoughts on the huge liquid fuel Missile displayed by North Korea. My estimates are likely within a plus/minus 10%, and loaded with some basic engineering assumptions. Much remains to be learned.... 1/n

The TEL has 11 axels, two more than Hwasong-15 TEL which is about 22m. These large vehicles are designed to be modular, so two additional axels, roughly 1.8 -2.0 m in length, were likely inserted, giving a new length of 25-26 m. The missile is about the same, 25-26 m long. 2/n
Diameter is more difficult to estimate from photos, but seems to be between 2.5 and 2.9 m. Resulting in a missile lift-off mass of 100-150 tonnes. Let’s take the middle values, 2.7m diameter and mass of ~125 tonnes. 3/n
Further assume the missile’s first stage is powered cluster of four RD-250 type chambers/engines for total sea level thrust of ~160 tonnes. This is twice that of the Hwasong-15. Lift off acceleration is then about 1.3 Gs, or thereabouts. Reasonably typical value for ICBMs. 4/n
If these estimates are close to reality, the missile, in principle, could deliver 2000 -3500 kg to any point on CONUS. This is more capable than Soviet R-16 or R-26 ICBMs that we’re never deployed. These systems had a first stage diameter of 2.7m, tho 2nd stage was smaller 5/n
Further, the old Soviet design had slightly less powerful, four chamber predecessor engines to the RD-250. 6/n
If this new missile uses auxiliary steering engine on F/S the throw weight grows. But, big question centers on S/S propulsion. Perhaps a Modified single chamber RD-250 with nozzle extensions? Performance estimates will vary significantly based on S/S assumptions. End.

A quick thread on #Myitsone dam & #MyanmarChinaRelations in light of the SAC announcement that they would be restarting some stalled Chinese projects in Burma. This announcement has led to speculation about Myitsone, which has been suspended since 2011. Let’s go! ➡️ China has


consistently misunderstood & underestimated popular opposition to Myitsone. First and foremost, to the Burmese people, this is about the “mother river” of Burma - the Irrawaddy- and it’s nearly sacred importance to them as a lifeline of their country. This is what drove the

organic anti-dam movement that started locally in Kachin but +/- 2007 was effectively picked up & nationalized by Burmese environmental CSOs. Instead of understanding this, the Chinese lashed out and blamed the United States when Thein Sein suspended the project. I assure you

the USG was as surprised as China when the project was suspended. But China never believed it was truly the desire of the Burmese people that stopped the project. Today, the dam doesn’t make sense economically for Beijing & will definitely alienate Burmese, yet they stubbornly

continue to push it. Why? Let’s unpack a bit further. In addition to Myitsone, there were other campaigns & protests targeting Chinese projects such as Letpadaung copper mine & Kyaukphyu pipeline, port & SEZ. While these campaigns had varying levels off effect, none was as

Decoded his way of analysis/logics for everyone to easily understand.

Have covered:
1. Analysis of volatility, how to foresee/signs.
2. Workbook
3. When to sell options
4. Diff category of days
5. How movement of option prices tell us what will happen

1. Keeps following volatility super closely.

Makes 7-8 different strategies to give him a sense of what's going on.

Whichever gives highest profit he trades in.


2. Theta falls when market moves.
Falls where market is headed towards not on our original position.


3. If you're an options seller then sell only when volatility is dropping, there is a high probability of you making the right trade and getting profit as a result

He believes in a market operator, if market mover sells volatility Sarang Sir joins him.


4. Theta decay vs Fall in vega

Sell when Vega is falling rather than for theta decay. You won't be trapped and higher probability of making profit.
