Arjun opened his screen on a quiet Tuesday and lost his first two trades inside an hour. Nothing dramatic, about Rs 1,800 gone, a normal bad morning. But it stung, and the sting said get it back. So he took a bigger trade to make up for it, and lost. Then a bigger one, angry now, and lost again. By lunch he had taken nine trades instead of his usual three, each one larger and looser than the last, and turned a Rs 1,800 morning into a Rs 22,000 hole. The trades were not the disaster. The missing line that said "stop after a bad morning" was the disaster.

Almost every blown account has a day like Arjun's at its centre. Not a single catastrophic trade, but a small loss that was allowed to keep going. The fix is boring and it works: decide, in advance, the most you will lose in a trade, in a day, in a week, and in a month. Write the numbers down. When you hit one, you are done for that period. No exceptions, no "one more". This chapter shows you the four layers and gives you a limit sheet you can copy.

The four layers of loss limits

Think of your loss limits as boxes inside boxes. The smallest is a single trade. A handful of trades sit inside a day. Days sit inside a week. Weeks sit inside a month. Each outer box is a tripwire that catches you when the inner ones did not.

Loss limits are boxes inside boxes Per month - e.g. -10% (then step back and review) Per week - e.g. -6% (then done for the week) Per day - e.g. 3 losses or -3% (switch off) Per trade - e.g. 1% the limit from position sizing
Each outer box catches the damage when the inner limit was not enough.

The numbers above are examples to make it concrete, not advice for your account. Pick your own and keep them small. Let us walk each layer.

Max loss per trade

You already met this in position sizing: before you enter, you decide the most this one trade can cost you, usually a small slice of your capital like 1%. On Rs 1,00,000 that is Rs 1,000. Your stop-loss and your quantity are set so that if the trade goes wrong, you lose about Rs 1,000 and no more. This is the foundation. Every other limit is built on top of it. If you do not have a firm per-trade loss, the bigger limits cannot hold, because you never know how much a single trade can take from you.

Max loss per day: the daily stop

The daily stop is the layer Arjun was missing, and it is the one that saves accounts. It is a single rule: after a set amount of damage in one day, you stop trading for the day. You can define it two ways, and using both is fine.

  • By count: stop after 3 losing trades in a row (or in a day).
  • By rupees or percent: stop when the day's loss hits, say, 3% of capital, about Rs 3,000 on Rs 1,00,000.

Whichever comes first, you switch off. Close the platform. The reason is not the money you have already lost, that is gone either way. The reason is the state you are in. After a few losses your brain is tilted: heart rate up, judgement narrow, hungry for revenge. This is the exact moment you take your worst trades. The daily stop pulls you away from the screen before the tilted brain can do real damage. A bad day capped at -3% is a footnote. A bad day with no cap is how Arjun got to -22%.

Same bad morning, two endings start -3% morning ---------------------------------- close daily stop hit - switch off flat for the rest of the day no stop: -22% "one more to get it back"...
The two paths are identical until the stop. After that, one trader is safe and the other is digging.
Common mistake

The classic killer is "one more trade to get it back." You hit your bad patch, and instead of stopping, you size up to recover the loss in a single shot. This is revenge trading, and it is a spiral: the bigger trade loses, so the next one is bigger still, and the tilt deepens with every loss. You are no longer trading a plan, you are gambling to feel better. The better move is brutally simple: the moment you hit your daily stop, you are done, even if it is 9:45 in the morning. The market is open tomorrow. Your capital needs to still be there to use it.

Max loss per week and per strategy

A week can quietly bleed even when no single day breaks your daily stop. Three days at -2% each is -6% for the week with not one "bad day" to point at. So set a weekly limit too, perhaps twice your daily figure, around -6% on our example account. Hit it, and you are done until the next week. A losing week is often a sign the market has changed character or that you are off your game, and a few days away is cheaper than forcing trades into conditions that no longer suit you.

If you trade more than one approach, give each its own per-strategy limit. Say you run a trend strategy and a quick scalping strategy. If scalping loses for two weeks straight, you pause that strategy and review it, without dragging down the one that is still working. Per-strategy limits stop a single broken method from quietly draining the whole account while the averages hide it.

The monthly circuit breaker

The monthly limit is the deepest tripwire, and it means something different from the others. A daily stop says "rest tonight." A monthly stop says "step back and review." If your account is down, say, 10% for the month, you stop trading real money for the rest of that month. This is not just a cool-off. It is a signal that something needs fixing: your edge may have faded, your sizing may be too large, the market may not suit your style right now, or your discipline has slipped. You go back to your trade log, study what went wrong, and if you want to keep practising, you do it in sandbox trading (analyzer mode in OpenAlgo) where mistakes cost nothing. You return next month, smaller and calmer.

Key idea

Loss limits are decided when you are calm and enforced when you are not. Per trade, per day, per week, per month: each is a number you set in advance and obey without negotiation. The tilted brain in the moment will always argue for "one more". The written limit is you, at your best, overruling you at your worst.

Why it must be written down in advance

Here is the uncomfortable truth: in the heat of a losing streak, your brain becomes a brilliant lawyer for "one more trade". It will find a setup. It will tell you this one is different, the loss was bad luck, you are due a winner. Every word of it feels reasonable. That is exactly why the decision cannot be made in the moment. A limit you set on a calm Sunday, in plain numbers on paper, is immune to the lawyer. When the screen says you are at -3%, there is nothing to debate. The rule already decided. You just follow it.

Your limit sheet

Fill this once, keep it where you trade, and check it before and during every session. Numbers shown are examples on a Rs 1,00,000 account, not advice, write in your own.

Limit Example rule Your number When you hit it
Per trade 1% (Rs 1,000) ______ Take the stop, move on
Per day 3 losses or -3% (Rs 3,000) ______ Switch off for the day
Per week -6% (Rs 6,000) ______ Done until next week
Per strategy -X% over Y weeks ______ Pause and review that strategy
Per month -10% (Rs 10,000) ______ Stop, review, sandbox only

A simple pre-session checklist:

  • I know my per-trade rupee risk before I enter anything.
  • My daily stop (count and rupees) is written down for today.
  • I will switch off the moment I hit it, no "one more".
  • I know my week-to-date and month-to-date loss right now.
  • If I am near a weekly or monthly limit, I trade smaller or not at all.

Limits for each type of market participant

The idea of a pre-set loss limit is universal, but what you cap and how tight you set it changes with what you do.

User type Tightest limit that matters Typical example Why
Long-term investor Per-position size, not a daily stop Cap any one stock at, say, 5-10% of the portfolio No day-trading, so the risk is concentration, not a bad session
Active trader The daily stop 3 losses or -3% a day, -6% a week Tilt and revenge trading are the main account-killers
F&O / futures trader Daily plus a hard monthly cap -3% day, -8% to -10% month Leverage means a bad run drains capital far faster
Option seller Per-position loss cap, not just per day Exit a short if loss hits 2-3x the premium taken Rare large losses, so the danger is one trade, not many small ones

When this fails

Limits control the harm you do to yourself; they cannot control the market. A daily stop does not protect you from an overnight gap or a sudden event that moves price before your stop can fill, that is gap risk, covered separately, and it can blow past a per-trade limit in one move. Limits set too tight fail in a different way: a 1% daily stop on a strategy whose normal swings are 2% will stop you out on ordinary noise, every day, and you never give a sound method room to work. The cure is to size the limits to your real volatility, loose enough to breathe, tight enough to save you.

The biggest failure, though, is not the numbers. It is breaking your own rule "just this once". A limit you override is not a limit, it is a suggestion, and suggestions do not survive a tilted brain. The discipline to actually switch off is the whole skill. And none of these example figures are personalised advice; they are a framework. Your real numbers depend on your capital, your strategy and what you can genuinely sit through. Set them when calm, write them down, and let them rule you when you are not.

Quick self-check

1. What are the four layers of loss limits, from smallest to largest?

Per trade, per day, per week and per month. The per-trade limit comes from position sizing; each larger layer is a wider safety net that catches damage the inner limit did not stop.

2. Why is the real purpose of a daily stop not about the money already lost?

The money is gone either way. The daily stop exists to pull you away from the screen before your tilted, revenge-seeking brain takes even worse trades. It protects your judgement and your remaining capital, not the loss you already took.

3. What is the "one more trade to get it back" spiral, and what stops it?

It is revenge trading: sizing up after a loss to recover in one shot, which usually loses bigger and deepens the tilt. A pre-set daily stop that you obey without exception stops it, you switch off the moment you hit it, even early in the day.

4. Why must loss limits be decided in advance and written down, not chosen in the moment?

In a losing streak the brain argues brilliantly for "one more trade", and every reason feels valid. A number you fixed when calm removes the debate, there is nothing to negotiate when the screen hits your written limit.

5. How does a monthly limit differ from a daily one?

A daily stop means rest tonight and return tomorrow. A monthly limit, say -10%, means stop trading real money for the rest of the month, then step back and review, because a deep monthly loss signals something needs fixing in your edge, sizing or discipline.
