Bull call spreads and bear put spreads are two of the most reliable defined-risk strategies in options trading. They let Indian crypto traders express a directional view with controlled cost and capped downside. Both fit naturally on CoinSwitch Pro’s Strategy Builder and work well for BTC and ETH options.
This guide explains both structures, walks through INR examples, and helps you decide which spread suits your market view at any given time.
What Is a Vertical Spread? (The Foundation)
A vertical spread is a two-leg options trade where you buy and sell options of the same type (both calls or both puts) and same expiry, but at different strikes. The spread “between” the strikes defines your max profit and max loss.
Vertical spreads come in two flavours: debit spreads (you pay net premium upfront) and credit spreads (you collect net premium upfront). Bull call and bear put are both debit spreads, ideal for moderate directional bets.
Bull Call Spread: Defined-Risk Bullish Bet
The bull call spread is the textbook bullish play with capped risk. You buy a call at one strike and sell a call at a higher strike.
Structure, Entry Cost, and Max Profit in INR
BTC at ₹65,00,000. Build a weekly bull call spread:
- Buy ₹65,00,000 call for ₹1,80,000
- Sell ₹67,00,000 call for ₹80,000
Net debit (cost): ₹1,00,000.
If BTC closes at or above ₹67,00,000 at expiry: max profit = (₹67,00,000 minus ₹65,00,000) minus ₹1,00,000 = ₹1,00,000.
If BTC closes at or below ₹65,00,000: max loss = ₹1,00,000 (the premium paid).
Breakeven: ₹66,00,000 (long strike plus net debit).
Ideal Market Conditions: Moderately Bullish, Not FOMO
Use a bull call spread when you expect BTC to move higher but not explosively higher. If you think BTC could go to ₹80,00,000, a single long call may be better because the spread caps your upside.
The spread shines when your view is “BTC will move from ₹65 to ₹67 over the week.” The capped upside is acceptable because you do not need more.
Step-by-Step Setup on CoinSwitch Pro
Open the BTC options chain on CoinSwitch Pro. Select the weekly expiry. Open the Strategy Builder. Add the buy leg at your lower strike (e.g., ₹65,00,000 call, BUY). Add the sell leg at your higher strike (e.g., ₹67,00,000 call, SELL). The builder shows net debit, max profit, max loss, and breakeven.
Place as a combined order. Avoid legging in unless you are an experienced trader, because BTC can move between the two fills.
Bear Put Spread: Defined-Risk Bearish Bet
The mirror image. You buy a put at a higher strike, sell a put at a lower strike. Net debit. You profit if BTC falls toward or through the lower strike.
Structure, Entry Cost, and Max Profit in INR
BTC at ₹65,00,000. Build a weekly bear put spread:
- Buy ₹65,00,000 put for ₹1,80,000
- Sell ₹63,00,000 put for ₹80,000
Net debit: ₹1,00,000. Max profit (if BTC at or below ₹63,00,000): ₹1,00,000. Max loss (if BTC at or above ₹65,00,000): ₹1,00,000.
When Bear Put Spreads Beat Simply Buying a Put
A long put can pay off bigger if BTC crashes hard. A bear put spread caps that. So why use the spread?
Cost. A long ATM put on weekly BTC can cost ₹1,80,000. The spread cuts the cost in half. If your view is a measured move down (not a crash), the spread offers better capital efficiency.
You also benefit from less IV exposure. The short leg’s negative Vega partially offsets the long leg’s positive Vega, so an IV crush hurts less.
Bull Call Spread vs Bear Put Spread: Direct Comparison Table
| Feature | Bull Call Spread | Bear Put Spread |
|---|---|---|
| Market view | Moderately bullish | Moderately bearish |
| Structure | Buy low call, sell high call | Buy high put, sell low put |
| Net cost | Debit | Debit |
| Max profit | Strike width minus debit | Strike width minus debit |
| Max loss | Net debit paid | Net debit paid |
| Breakeven | Lower strike + debit | Higher strike minus debit |
| Theta | Slightly negative | Slightly negative |
| Vega | Slightly positive | Slightly positive |
Margin Requirements, Max P&L, Break-Even Calculation
Both spreads are debit trades. The margin equals the net debit you pay (since that is your max loss). CoinSwitch Pro will display the exact margin requirement in the Strategy Builder.
Max P&L and breakeven follow the same formula structure for each. The math is symmetrical.
Strike Selection: Narrow vs Wide Spreads
This is where most traders go wrong.
Narrow Spread = Cheaper but Lower Reward
A narrow spread (strikes ₹1,00,000 apart) costs less but caps your max profit quickly. Good for short-term, modest-move expectations.
Example: ₹65,00,000 / ₹66,00,000 bull call spread. Net debit maybe ₹40,000. Max profit ₹60,000. You doubled your money on a 1.5% move.
Wide Spread = Higher Reward but More Capital Tied Up
A wide spread (₹3,00,000 apart) costs more, ties up more capital, but pays better if you are right.
Example: ₹65,00,000 / ₹68,00,000 bull call spread. Net debit maybe ₹1,20,000. Max profit ₹1,80,000. You earned 1.5x on the trade if BTC closes above ₹68,00,000.
In crypto, where moves are often big, wider spreads tend to outperform narrow ones over time. But position size accordingly.
Combining Spreads with Your Spot Holdings
Spreads aren’t just standalone trades.
Using a Bear Put Spread to Hedge an Existing BTC Position
If you hold 0.5 BTC and worry about a near-term downside, a bear put spread is a cheaper hedge than a long put alone.
Example: BTC at ₹65,00,000, you own 0.5 BTC (₹32,50,000 exposure). Buy a one-month ₹62,00,000 put, sell a one-month ₹58,00,000 put. Net debit might be ₹70,000. This covers your downside from ₹62,00,000 to ₹58,00,000.
If BTC crashes below ₹58,00,000, the spread is maxed out but your spot continues to lose. So this is partial protection, not full.
For full crash protection without the cap, see our guide on the protective put.
Tax on Vertical Spreads in India 2026
Each leg of the spread is a separate taxable event. Two legs at entry, two at exit, so four taxable events per round trip.
If your activity qualifies as VDA income, the 30% flat tax applies. If it qualifies as speculative business income, slab rates may apply in some interpretations. The 1% TDS rule applies on the gross proceeds of each leg.

Key Takeaways
Bull call and bear put spreads are the cleanest way to express a directional view in crypto options with defined risk. Both cap your loss at the net debit you pay. Both cap your max profit at the strike width minus the debit. Use them when you expect a moderate move, not a moonshot.
Build them on CoinSwitch Pro’s Strategy Builder. Choose strike widths based on the move size you expect. Wider for bigger expected moves, narrower for tight setups. And remember to factor in fees and tax friction when sizing positions.
FAQs
Q: When should I use a vertical spread instead of a single option? When your expected move is moderate (1% to 5%), when IV is high and a single option is expensive, or when you want a defined-risk version of a directional bet.
Q: Can I exit a vertical spread early? Yes. You can close both legs as a combined order on CoinSwitch Pro’s Strategy Builder at any time before expiry. Profit-taking at 50% of max profit is a common rule.
Q: What is the breakeven on a bull call spread? Lower strike plus net debit paid. So a ₹65,00,000 / ₹67,00,000 spread with ₹1,00,000 debit breaks even at ₹66,00,000.
Q: Does the short leg get assigned early? Crypto options on CoinSwitch Pro are typically European-style (no early assignment) or settled at expiry. Check the specific contract terms before trading.
Q: Are vertical spreads good for beginners? Yes. They are one of the safest entry points into multi-leg strategies because risk and reward are defined upfront.
Q: How is a vertical spread taxed in India? Each leg is a separate taxable transaction. The 30% flat VDA tax applies if classified as VDA income, with 1% TDS on gross proceeds per leg.
