The biggest mistake anyone makes is to choose zerodha as their broker I don’t have much complain about zerodha but only complain is that they launch features very late even if a little button is to be repositioned it takes 2 to 3 months for them to update it.

The biggest lesson for me: your first job isn’t to make money, it’s to survive long enough to learn. Most beginners focus on finding the perfect strategy when they should be focusing on position sizing, risk management, and staying consistent. In F&O, protecting capital is a strategy in itself.

Yes zerodha is gone, now dhan is emerging. Dhan has good features on f&o than zerodha especially 8n live market dhan is good

Bro I am sorry for my post I think dhan is introducing new features very fast no doubt but broo there are lots n lots of bugs and for that reason a feature that looks useful may put you into any new trouble because of bugs I think that is the reason zerodha is slow in feature releasing as they release something when it’s purely useful with low bugs and glitches zerodha features are polished

Dhan has lot of features but they have bugs that may cause you into trouble.

Zerodha has less features but it’s every feature has zero bugs or glitches and it is perfect.

I’m sure everyone has a different journey in F&O, but I just wanted to share mine.

When I first started, learning concepts like Open Interest, long build-up, short build-up, option chain, and Greeks felt exciting. After a while, you start understanding the market and think, “Okay, I think I’ve finally figured this out.”

I feel most beginners, including a lot of my friends, start with just one lot, and I think that’s the right way to begin. The problem starts after 2–3 profitable trades. Confidence slowly turns into overconfidence, and you begin increasing your position size because it feels like you’ve understood the market.

That’s where reality hits.

As retail traders, we often forget who we’re competing against institutions, professional traders, algorithms, and people who’ve spent years in the markets.

Then comes the phase almost every beginner goes through. One week you’re following price action, the next you’re trying a new strategy from YouTube, then scalping. Every losing streak makes you think the strategy is the problem, when in reality it’s often a lack of consistency and discipline.

One habit that genuinely helped me was maintaining a handwritten trading journal. Writing down why I took a trade, how I felt, and what I learned helped me understand my mistakes and control my emotions much better.

Another thing that helped was Sensibull’s virtual trading. Whenever I wanted to test a new strategy or wasn’t confident enough to take a real trade, I’d first practice it there. It gave me confidence without risking capital.

Of course, there were times when a strategy worked well in virtual trading but failed in the real market. That’s when I realized the real challenge wasn’t the strategy it was controlling myself. I would end up taking extra trades to recover losses, which only made things worse.

What eventually worked for me was keeping a few simple rules: a maximum of four trades a week, a predefined loss I’m willing to accept, and never moving my stop-loss.

I also tried features like Kill Switch, but personally I don’t think technology alone solves the problem. If your mindset isn’t disciplined, you’ll eventually find another way to keep trading. The real challenge is training yourself to stop when your trading plan says stop.

Anyone can learn concepts like long build-up or short build-up in a few days. Learning to stay patient after three winning trades or three losing trades that’s what takes months, sometimes years.
