How to manage risk in trading, for Indian retail traders

Ask ten traders what risk management means and you will get ten answers about mindset. Ask them what their per-trade risk is in rupees and most will not have a number.

That is the whole problem. Risk management is not an attitude. It is four numbers you work out once, write down, and then follow. This post is how to work out those four numbers from your own account.

No theory. Just the arithmetic.

Number 1: Your per-trade risk

How much you are willing to lose on any single trade.

The standard answer is one to two percent of capital. For most Indian retail traders with a small account, one percent is too small to be practical and five percent is too large to survive a bad week.

Work it out like this. Take your trading capital, not your net worth, not the money you might add later. The money in the account right now.

On ₹2,00,000 of capital:

• 1% is ₹2,000 per trade
• 2% is ₹4,000 per trade

Now do the survival check. How many losses in a row can you take before it hurts enough that you stop thinking straight? Six or seven in a row happens to everybody, more often than people expect. At 2% that is a 12% drawdown. Painful, recoverable. At 5% it is a 30% drawdown, which is where people blow up accounts trying to get it back.

Pick 1% or 2%. Write the rupee figure, not the percentage. "₹4,000" is a number you can check against a screen. "2%" is a sum you will not do at 1 PM.

Number 2: Your daily loss limit

How much you are willing to lose across the whole day before you stop.

The clean way to set this is as a multiple of your per-trade risk. Two to three times is right for most people.

At ₹4,000 per trade:

• 2x is ₹8,000
• 3x is ₹12,000

Why a multiple and not a round number? Because it ties your day to your actual strategy. Three losses in a row is a normal bad day for most systems. If your daily limit is less than three trades' worth of risk, you will hit it on ordinary days and start ignoring it. If it is more than four trades' worth, it is not really protecting you, it is just a number you write down.

Set it at 3x your per-trade risk. Then sanity check it against your monthly income. If hitting the limit twice in a week would genuinely change how you live, it is too big regardless of what the arithmetic says.

There is more detail on this, including how to handle a growing or shrinking account, in how to set a daily loss limit you cannot talk yourself out of, and you can run your own figures through the loss limit calculator.

Number 3: Your position size

How many lots, worked backwards from Numbers 1 and 2.

This is the step almost everyone gets backwards. They decide the quantity first, based on what feels right or what they can afford, and then find out what they risked afterwards.

Do it the other way round. The formula:

Quantity = per-trade risk ÷ (entry price minus stop price)

An example in options. You are buying a Nifty call at ₹120. Your plan says you exit at ₹95. Your per-trade risk is ₹4,000.

• Risk per unit: 120 minus 95 = ₹25
• Quantity: 4,000 ÷ 25 = 160 units
• Nifty lot size is 75, so 160 ÷ 75 = 2.1 lots

Take 2 lots, not 3. Always round down. Rounding up means the stop you planned now costs more than the risk you allowed, which quietly breaks Number 1 on every single trade.

This is why the same trader takes 4 lots on one trade and 1 lot on another, and why that is correct rather than inconsistent. The stop distance changed, so the size changed. The rupee risk stayed the same. That is the whole point.

Number 4: Your maximum trades per day

A count, not just rupees.

Your daily loss limit is a backstop. It only fires after the money is gone. A trade count fires before, on the attempt.

Take your last thirty days of trades, find the median trades per day, and add one. That is your number. Use the median rather than the average, because the average is inflated by exactly the runaway days you are trying to prevent.

The reason a count works when a rupee figure does not is that you cannot negotiate with it. "I am down ₹9,000 but the setup is really good" is an argument you can win against yourself. "I have taken six trades" is not an argument, it is a fact. More on this in how to stop overtrading.

The one habit

Four numbers on paper protect nobody. The habit is this:

Write all four down before 9:15, and check them at 1 PM.

Not once when you read this post. Every trading day, on paper, before the market opens. It takes ninety seconds:

Date: ___
Per-trade risk:  ₹___
Daily loss limit: ₹___
Max trades:       ___
After a loss, wait ___ minutes

The morning version of you is a much better risk manager than the 1 PM version. The written page is how the morning version gets a say when it matters.

What usually goes wrong

The stop moves. You set an exit, price approaches it, and you decide the level was "too tight". Once you move a stop, you no longer have a per-trade risk, you have a hope. If you find yourself doing this often, the honest fix is a wider stop and a smaller size from the start, not a stop you move under pressure.

Averaging down. Adding to a loser feels like improving your price. It is doubling your risk on the one trade that is already telling you that you were wrong. Your per-trade risk was fixed at entry. Adding breaks it.

Recalculating the limit mid-session. If you are down ₹11,000 against a ₹12,000 limit and you find yourself doing sums about whether the limit was "really" right, you are not doing risk management, you are looking for permission. Note it, stop, and revisit the number on the weekend when nothing is at stake.

Nothing enforces any of it. This is the big one. All four numbers depend on you noticing that you crossed a line, at the exact moment you are least able to notice.

That gap is why we built LossGuardian. It reads your trades from your broker as they happen, tracks them against the limits you set that morning, and puts a full-screen alert in front of you when you cross one. Not a corner notification you swat away without reading. Something that interrupts, and quotes your own rule back at you.

It is read-only by design. It cannot place, change or cancel an order, and it will never square off a position for you. That is a deliberate choice, not a missing feature.

Start here

If you do nothing else from this post, do this today:

1. Open your broker tradebook and find your median trades per day.
2. Work out 2% of your current capital. That is your per-trade risk.
3. Multiply by three. That is your daily loss limit.
4. Write all three on paper tonight, before tomorrow opens.

That is the entire system. Everything else is refinement.
