Thread : An expensive lesson in Risk Managmenent 🧵

1) I would like to share my nerve wracking experience that forever imbibed in me the importance of risk management.

On Aug 2016, I lost -20L in a minute,what lessons I learnt from this incident & how did I bounce back !
2) On August 2016, I suffered my highest intraday loss of 18 lacs due to a unknown risk.
I had shorted Just Dial 500 CE & was in a profit of 1.3 lacs at 3:19 pm. But to my dismay, at 3:20 pm, I saw a whopping loss of 18 lacs. In less than 60 seconds, I had lost over 20 lacs.
3) I had huge qty in Just Dial CE but as my position was huge and Just Dial being an illiquid script. My position got squared from 0 to 10 Rs. I was in 1.3 L profit at 3.19 & 3:20 -18 L.

Lost almost 20 L in a min

Check my email to @zerodhaonline and their reply to understand
4) I was totally upset as I never thought that I could lose so much due to illiquidity.

There was nothing wrong with system or risk management but this was a risk which I was never aware.

This made me believe in risk management ever then before.
5) That was quite a hard time for me and I started doubting my trading abilities.

I couldn’t digest the fact that in 60 seconds I lost -20 L due to illiqudity :(

This was the lowest point of my trading career and the future looked gloomy☹️ as confidence was badly shaken !
6) Inspite of the huge loss, I kept following my system.

Market were kind🙏 & I made the highest ever profit in % term in next 3 months.
Almost 75L profit in 3 months from sept 2016 to Dec 2016.

Check the PnL attached !
7) I thanked God for helping me sail through the painful drawdown.

After this incident, I vowed that I’ll never take the markets lightly and always manage my risk at all times.
8) On 21st Sept 2018, I had sold 330 PE overnight and YesBank opened 10% lower and closed the day at -33%. But I survived as I bought 320 put as protection.

If I had not bought 320 PE then would have lost 10 L

I managed overnight risk also after an expensive lesson in Just Dial
9) Ms. Nirmala Sitaraman Candle

On 21st Sept 2019, BankNifty rallied almost 10% intraday with huge IV spike in calls.

I had 27200 CE sold and booked loss in that at 220. The same option was trading at 2230 few hours later.

Would have lost heavily if I had not managed my risk
10) Demonetisation
- Surgical Strike
- Flash Crash in March 19
- Lower Circuit on index in March 20

Have survived all major black swans without any major loss.

After making huge losses at the start of my career, I have realised that good trading is all about managing risk.
11) I have been in drawdowns several times since then but never lost the convinction to follow my systems.

Drawdowns are inevitable for a trader.
We can only manage risk & follow our systems.
Never take markets lightly & never make a loss so big that affects you emotionally
12) Consistent success in trading lies in effective management of risk & sticking to your system even through prolonged periods of drawdown.
13)Rules I follow to manage Risk

- Never open any trade without knowing the initial risk ( R)

- Define PnL in terms of R

- Limit losses under 1 R and profits should be >1 R
14) Read this book

Van Tharp’s Definitive guide to position sizing

It’s a great book risk management & position sizing

amazon.com/Definitive-Gui…
15)Reason for this thread :

-Focus on risk management & types of risks
-Backtest &Follow your systems with conviction
-Don’t be afraid of losses & drawdown as no system can make money all the time

Goodluck on your Trading Journey !

-End

Mastering the Trade -  Key Lessons from John Carter
Trading isn’t about luck. It’s about discipline, risk management, and repeatable setups. Here’s what every trader should know 🧵 Image
1) Trading is a skill, not a gamble
Success comes from strategies you can repeat, not from guessing market moves.
Control what you can do with your entries, exits, and risk.
2) Mindset is everything
Most traders fail due to emotions, not setups.
Stick to your plan
Journal every trade: why you entered, what went right/wrong, how you felt

Trading isn’t just “buying and selling stocks.”
It’s about knowing yourself, managing risk, controlling emotions, and protecting your capital.
If you’re serious about trading, study your game inside out — not just setups and profits.

A thread 🧵 Image
Trading success isn’t about the best strategy, it’s about mastering yourself:
Discipline. Patience. Consistency. Image
1. Discipline – follow your plan
Successful traders stick to their rules no matter what the market does. Impulse decisions and emotional trades are the fastest way to lose. Discipline keeps you consistent.

Warren Buffett nearly went bankrupt in 1962
His biggest bet was burning $4M a month. Bankruptcy was weeks away
Then a man named Harry Bottle saved his career in 6 days
The untold story of Buffett’s riskiest investment  🧵Image
1) Young Buffett thought he struck gold
He bet big on Dempster Mill, a struggling windmill manufacturer
Stock price: $18/share
Book value: $72/share
A 75% discount is the perfect Ben Graham-style bargain
By 1961, he owned 70% of the company Image
2) But the numbers were lying
Dempster made up 21% of Buffett’s fund
Cash: $166K
Debt: $2.3M
$4M of inventory sat rotting in warehouses some of it since 1909
Bankruptcy was weeks away. Buffett was trapped Image

Trading in the Zone – Mark Douglas
Most traders lose not because of bad strategies… but because of bad mindsets.
Mark Douglas explains why trading psychology is the real edge.
Here’s the full breakdown 🧵 Image
1)The Core Idea

Trading isn’t about predicting the market.
It’s about learning to:
- Think in probabilities
- Control your emotions
- Execute with discipline
Success = consistency, not prediction.
2) Why Traders Fail

Douglas says most traders fall into 3 traps:
- Need to be right → They can’t accept losses.
- Random reinforcement → A few lucky wins create overconfidence.
- Emotional trading → Fear, greed, and hope drive decisions.
Result: they sabotage themselves, even with good strategies.

Are markets really being manipulated on the expiry day ?

A detailed thread🧵 Image
1) Lets see last Nifty expiry on 8th May

We had war tensions
Lot of uncertainity going on

But straddle at 12 pm was quoting at 19😳

Infact 24400 CE had OI of 7.5 crore
This is highest ever OI on a single strike
2) This indicates that someone has opted for a quite expiry and inspite of the uncertainity is sure that 24400 CE won’t be taken out.

But now contrast this to yesterday(15th May)
Straddle was at 175 at 12 pm

And IV was spiking since morning
