Hi @Everyone,
If we want to start algo trading with a relatively small capital base like ₹1 lakh, we need a setup that does two things well. First, it must fit comfortably within the capital limit. Second, it should offer a strong probability of profit so that we are not depending on a few lucky trades.
One practical way to do that is with DOS, or Directional Option Selling . This is a structured options strategy built around market direction, delta based strike selection, and strict risk management. When used properly, it can be traded with less than ₹1 lakh margin and can be designed around a probability of profit above 80%.
What is Directional Option Selling?
-
DOS stands for Directional Option Selling . The idea is simple.
-
We first identify the market direction.
-
Then we sell an out of the money option in that direction bias.
-
We hedge it by buying a farther out option.
-
We manage the trade with predefined profit booking and stop loss rules.
This is not a random option selling approach. It is rule based. That makes it suitable not only for manual execution, but also for algo trading and automation later.
Step 1: Find the Direction of the Market
Since this is a directional strategy, the first job is to decide whether the setup is bullish or bearish.
A simple way to do this is by using Supertrend with settings 10 and 3 . For intraday trading, the setup uses a 5 minute timeframe .
-
If Supertrend is green , we treat the market as bullish.
-
If Supertrend is red , we treat the market as bearish.
This directional filter decides whether we work with puts or calls.
How the directional logic works
-
Bullish setup: sell a put and buy a lower strike put as hedge.
-
Bearish setup: sell a call and buy a higher strike call as hedge.
So if the market is bearish, we operate on the call side. If the market is bullish, we operate on the put side.
Step 2: Select Strikes Using Delta
The real edge in this setup comes from delta based strike selection .
Instead of choosing strikes by guesswork or by fixed point distance, we choose them based on option delta.
Strike selection rules
-
Sell the option with delta near 0.20
-
Buy the hedge option with delta near 0.10
That means:
-
In a bearish trade , we sell the call with delta close to 0.20 and buy the call with delta close to 0.10.
-
In a bullish trade , we sell the put with delta close to 0.20 and buy the put with delta close to 0.10.
This creates a hedged short option structure with a defined risk profile.
Example of the Setup
Suppose the market direction is bearish based on Supertrend. In that case:
-
We go to the option chain.
-
We locate the call option with delta closest to 0.20 .
-
That becomes the short call strike .
-
Then we locate the call option with delta closest to 0.10 .
-
That becomes the hedge call strike .
In the example discussed, the short strike was around 23350 and the hedge strike was around 23750 . The exact strikes will always depend on the option chain at that moment, which is why delta based selection is more robust than choosing arbitrary levels.
Can This Be Traded with ₹1 Lakh?
Yes, that is one of the main reasons this setup is useful for beginners exploring algorithmic trading with small capital.
In the example, the margin requirement was about ₹63,000 . That is comfortably below ₹1 lakh and still leaves extra capital in the account.
That leftover margin matters. We do not want to use the full account balance on one structure. Keeping buffer capital gives the trade room to function and avoids pressure from tight margin utilization.
Why this capital structure works
-
Margin stays below ₹1 lakh
-
Risk is hedged, not naked
-
There is still spare capital available
-
The setup can later be automated more easily because the rules are defined
Understanding the Payoff Profile
In the example setup:
-
Maximum profit: about ₹4,000
-
Maximum loss: about ₹21,000
-
Probability of profit: about 80%
That 80% figure is the reason this strategy is framed as a probability based setup. If we repeatedly take trades with similar conditions, we are aiming for a structure where most trades work and a smaller number of trades fail.
This does not mean every trade will win. It means the setup is designed so that the odds are tilted in our favour over a series of trades.
Why Delta Matters So Much
The confidence behind the 80% plus probability of profit comes directly from the delta we choose to sell.
Here is the rough idea:
-
0.20 delta gives a profit probability of roughly 80% or more
-
0.30 delta drops it closer to 70%
-
0.40 delta brings it near 60%
-
At the money options move toward a 50% style probability profile
This is why the strategy specifically uses the 0.20 delta for the short option. We are intentionally choosing a strike that gives a better chance of winning, even if that means the profit per trade is not very large.
That is an important mindset shift. We are not trying to maximize reward on each trade. We are trying to build a repeatable setup where the probability profile works in our favour.
Risk Management is the Most Important Part
Without risk management, option selling can become dangerous very quickly. A strategy may look safe because of its high probability, but if losses are left uncontrolled, one bad trade can erase many good ones.
That is why this setup defines both target and stop loss very clearly.
The risk management rule
Both target and stop loss are set at 70% of maximum profit .
Using the example:
-
Maximum profit = ₹4,000
-
70% of max profit = ₹2,800
So the trade rules become:
-
Book profit at ₹2,800
-
Exit at ₹2,800 loss
This gives a 1:1 risk to reward structure in actual execution, even though the full payoff graph may show a different maximum profit and maximum loss.
Why Book Profit at 70% of Maximum Profit?
This is where many traders make mistakes. They see that the strategy can theoretically earn ₹4,000, so they try to hold till the absolute maximum.
That usually is not worth it.
Once the position has already made around ₹2,800, a large part of the available profit has already been captured. From there, the extra gain left on the table is only about ₹1,200 in this example.
Keeping the trade open for that comparatively small remaining gain does not make much sense, especially in option selling where risk can change quickly.
So when a trade has already delivered around 60% to 70% of its possible best case profit, it is often smarter to close it, lock the gains, and move on. There will always be another trading day and another setup.
Why Stop the Trade at the Same ₹2,800 Loss?
The same discipline applies on the downside.
If the position reaches a loss of ₹2,800, we close it. We do not wait and hope.
Why? Because the total defined loss on the structure can be far larger. In the example, the maximum possible loss is more than ₹21,000. If we allow the trade to continue after the setup has already proven itself wrong, we expose the account to a much bigger drawdown.
So the stop loss is not arbitrary. It is there to prevent a manageable loss from becoming a damaging one.
In short:
-
If the trade makes ₹2,800, we exit.
-
If the trade loses ₹2,800, we also exit.
-
We stop trading that setup for the day and return fresh on the next opportunity.
Markets open every day. Opportunities do not disappear. Capital discipline matters more than forcing one trade to work.
This Strategy is Based on Probability, Not Huge Risk Reward
A lot of traders get obsessed with risk to reward alone. This strategy takes a different route.
Here, the edge does not come from chasing a 1:3 or 1:5 reward profile. The edge comes from taking a setup that is designed to win a high percentage of the time, while keeping individual losses controlled.
That is why the framework is built around:
** High probability entries*
-
Delta based strike selection
-
Defined hedging
-
Equal target and stop loss based on 70% of max profit
This is a different style of trading. We are playing the odds over a series of trades, not trying to hit one oversized winner.

Before Automating, Trade It Manually First
It is tempting to jump straight into algo trading, but that is usually the wrong sequence.
Before building automation, we should first understand how the strategy behaves in real market conditions. That means:
-
Manually backtesting the idea on historical charts
-
Applying it to current market sessions
-
Paper trading it before deploying real capital
This step builds intuition. We start understanding how often the signal appears, how the position reacts, how the exits feel, and whether the rules are practical to follow.
Only after gaining this experience does it make sense to automate the logic.
How the Algo Version Works
Once the strategy rules are clear, this setup is quite suitable for automation.
The algo logic is straightforward:
-
Check market direction using the predefined signal.
-
Pull the option chain.
-
Identify whether we need calls or puts based on the direction.
-
Find the strike with delta nearest to 0.20 for selling.
-
Find the strike with delta nearest to 0.10 for hedging.
-
Use those strikes to place the order structure.
For example, if the signal is bearish, the algo goes into the call option chain, searches for the call whose delta is closest to 0.20, and marks that as the short strike. Then it looks for the call whose delta is closest to 0.10 and marks that as the hedge strike.
That is the essence of delta based strike selection in an automated trading system.
What the Strategy Teaches About Algo Trading
This setup is a good starting point for algorithmic trading because it highlights the foundations of a proper trading system:
-
A clear entry condition
-
A repeatable strike selection rule
-
Defined capital usage
-
Preplanned exits
-
A structure that can be backtested and automated
That is exactly how beginners should think about small capital algo trading. Not as a shortcut, but as a process of converting a manual edge into a systematic one.
Final Takeaway
If we want to start algo trading with ₹1 lakh capital, we do not need a highly complex system. We need a disciplined one.
DOS, or Directional Option Selling, offers a simple framework:
-
Use Supertrend to define direction
-
Sell the 0.20 delta option
-
Hedge with the 0.10 delta option
-
Keep capital usage below ₹1 lakh
-
Target a high probability setup
-
Exit at 70% of max profit on both the upside and downside
From there, the right next step is not to rush into full automation. The right next step is to backtest it, paper trade it, and understand how it behaves. Once we have that experience, building the algo becomes far more meaningful and far more practical.
