The best strategy dies at the checkout. Picking the right Indian broker, understanding margin requirements, order types, and brokerage math — the practical details that separate paper trading from real trading.
| Broker | F&O brokerage | Best for |
|---|---|---|
| Zerodha | ₹20/order flat | Most retail traders. Kite is the gold standard. Free EOD data via NSE. |
| Upstox | ₹20/order flat | Similar to Zerodha. Slightly cheaper add-ons. |
| Angel One | ₹20/order flat | Good research, decent execution. Smart Options for multi-leg orders. |
| ICICI Direct | Higher (0.05% or ₹25) | Traditional broker, not cheapest but reliable execution. |
| Dhan | ₹20/order flat | Modern platform, good multi-leg builder, popular with options traders. |
| Fyers | ₹20/order flat | Best charting for options-focused technical traders. |
Recommendation for beginners: Zerodha or Dhan. Both have flat ₹20/order pricing, good UIs, and options-friendly interfaces.
Specifications change — always verify current lot sizes, expiry days, and margins with your broker before trading.
Brokerage: ₹20 per order (flat) STT (Securities Transaction Tax): 0.05% on sell-side of premium Transaction charges: NSE ~0.053% on premium GST: 18% on (brokerage + transaction) SEBI charges: 0.0001% on premium Stamp duty: 0.003% on buy-side (state-dependent)
You sell 1 Nifty ATM call for ₹150 (lot size 75 = ₹11,250 premium collected).
Sell-side cost: ~₹36
If you also buy back to close: another ~₹36. Round-trip: ~₹72 per lot.
Rule of thumb: budget ₹50-70 per lot round-trip. Multi-leg strategies scale up: iron condor = 4 legs = ~₹200-280 round-trip.
Options buying = you pay only the premium. No additional margin.
Options selling = you pay initial margin + exposure margin. Uses SPAN + Exposure formula.
| Position | Approx margin per lot |
|---|---|
| Sensex short call/put (weekly) | ₹1,10,000 – ₹1,50,000 |
| Sensex short strangle (weekly) | ₹1,80,000 – ₹2,40,000 |
| Sensex iron condor (200-wide wings) | ₹45,000 – ₹65,000 (bounded loss reduces margin) |
| Nifty short strangle (weekly) | ₹2,00,000 – ₹2,80,000 (new lot size 75) |
| Nifty iron condor (200-wide wings) | ₹60,000 – ₹85,000 |
| Bank Nifty short strangle (monthly) | ₹2,50,000 – ₹3,20,000 |
| Stock (Reliance) short call | ₹1,20,000 – ₹1,60,000 |
SEBI increased F&O lot sizes in November 2024 (Nifty 25→75, Bank Nifty 15→35, Sensex 10→20, etc.) to make F&O less accessible to small retail traders. Margins scaled up proportionally. If you have an older reference showing smaller margin numbers, those are outdated.
Iron condors and other defined-risk spreads have dramatically lower margin because your worst-case is capped.
Limit order (default): specify max buy price / min sell price. Fills at your price or better. Slower but no bad surprises.
Market order: fills immediately at whatever the current bid/ask is. Fast but risky in illiquid options (bad fills).
Stop-loss (SL / SL-M) order: converts to a limit/market when the trigger is hit. Essential for options selling — set a stop-loss automatically when you enter.
Bracket order (BO): enter + take-profit + stop-loss all in one. Great for directional trades.
Cover order (CO): enter + mandatory stop-loss. Zerodha’s most popular intraday setup.
Deep OTM weekly options can have huge bid-ask spreads (sometimes 30-50% of premium). A market order there gives you a terrible fill. Always use limit orders on options.
For iron condors, butterflies, straddles — placing 4 separate legs manually risks getting bad fills.
Use built-in multi-leg builders:
These execute all legs together (or nothing). Much better than legging in one order at a time.
Slippage: the difference between the price you see and the price you get. Worse on illiquid strikes, event days, and near expiry. Budget 1-2 ticks of slippage on Nifty; up to 5-10 on individual stock options.
Freak trades: Nifty options occasionally trade at wildly wrong prices for a few seconds due to fat-finger orders or algo glitches. If a limit order fills at a suspiciously good price, don’t celebrate — sometimes these get cancelled by the exchange.
Circuit breakers: stocks can hit upper/lower circuit and stop trading. Your options can become one-sided (only bids or only asks). Manage risk before this happens, not after.
Best times to enter/exit options:
Worst times:
Options trading is speculative business income (or non-speculative if F&O). Reported on ITR-3.
Every broker provides a contract note per trade and a P&L statement per FY. Download them monthly. Come tax season, you’ll thank yourself.
F&O turnover for tax purposes is NOT total notional. It’s the absolute sum of realized profits and losses, plus premium received on sold options.
F&O Turnover F&O Turnover = ΣGross Profits + ΣGross Losses (both as positive numbers) + Premium collected on options sold
Example: You had 3 F&O trades — +₹5,000, −₹3,000, +₹2,000, and you sold options worth ₹10,000 in premium.
Turnover = 5,000 + 3,000 + 2,000 + 10,000 = ₹20,000
This turnover figure is used for tax audit thresholds and section 44AD applicability.
Under Section 44AB (2024 rules):
For turnover < ₹2 crore, you CAN opt for presumptive taxation:
Most F&O traders do NOT use 44AD — instead they file regular ITR-3 with actual P&L.
Options traders don’t pay GST on their trading (it’s not a service). But:
Impact: letting an option expire ITM triggers STT on notional value, which can wipe out profits on marginal trades. Always close ITM options before expiry unless taking delivery deliberately.
Many retail F&O traders under-report or misreport their F&O activity. The Income Tax Department has explicitly warned traders — F&O losses shown incorrectly can trigger scrutiny. Report accurately even if it means you have to pay slightly more.
You now have the vocabulary, the strategies, the math, and the practical execution knowledge. Real trading is different from reading — start tiny, keep records, review honestly.
Good luck. Trade small, live long.
