Why do traders fail prop firm challenges? Rarely because they cannot read a chart. Most failures come from a small set of repeatable mistakes: not knowing the loss floors in rupees, risking too much on one idea, trading emotionally on expiry days, or misreading a rule. Each one is avoidable. This guide walks through 13 of the most common prop firm mistakes in Indian markets, what actually happens when you make them, and the fix for each.
01Why traders fail prop firm challenges
A prop firm challenge is an evaluation in which you trade simulated capital at live Indian market prices and must reach a profit target without breaching loss limits. At Greenwick, the 2-Step needs 8% in Phase 1 and 5% in Phase 2, with a 4% daily loss limit and an 8% static max loss. The 1-Step needs 10%, with 3% daily and 6% static max loss.
Those numbers are generous enough for a disciplined trader. What fails accounts is the gap between the plan and what happens at 10:47 on a Thursday when BANKNIFTY moves 200 points against you. The mistakes below fall into five groups: rule mistakes, sizing mistakes, timing mistakes, mindset mistakes and plan mistakes.
02Rule mistakes: floors, equity and trailing
1. Not knowing your floors in rupees
What happens: Traders know the limits as percentages but never convert them. In the middle of a fast move, "4%" means nothing. They only realise how close they are when the account closes.
The daily floor resets at 09:15 IST from the previous day's closing balance. The max loss floor stays at ₹9,20,000 even after ₹1L of profit.
The fix: Before 09:15 IST, write both floors in rupees on paper. Check your dashboard to confirm them. Size every trade from those numbers.
2. Ignoring open P&L (equity)
What happens: Loss limits are measured on equity, which includes open P&L. A trader with ₹15,000 booked loss holds an option position that is ₹26,000 down on paper. Equity is now ₹41,000 below the day's start, past the ₹40,000 limit. The account closes, even if the option recovers five minutes later.
The fix: Treat open loss as real loss. Set your stop so that booked loss plus the worst case on every open position stays well inside the daily limit. Touching a floor at any moment closes the account.
3. Misunderstanding trailing drawdown on Instant
What happens: The Instant plan has a 5% trailing max loss. The floor moves up with your highest equity, then locks permanently once it reaches the starting balance. Traders used to static floors give back a winning run and are surprised to find the floor much closer than they thought.
After the floor locks at the starting balance it never moves again.
The fix: Check the current trailing floor every morning, not just the starting one. Reduce size after a strong run until the floor locks. The drawdown explained guide shows both floor types in detail.
03Sizing mistakes that break accounts
4. Risking too much per trade
What happens: A trader risks ₹20,000 per trade on a ₹10L 2-Step. Two normal losses use the entire ₹40,000 daily limit. There is no room for a bad morning.
Both traders have the same strategy. Only one of them survives an ordinary losing streak.
The problem compounds on the max loss floor. Trader A can lose the whole ₹80,000 static buffer in four bad trades spread over a week. Trader B would need more than a dozen. Win rate matters far less than how many losses you can survive in a row.
The fix: Risk a small fraction of the daily limit per trade, so that three or four consecutive losses still leave you above the floor. On a ₹40,000 daily limit, many disciplined traders risk ₹5,000 to ₹8,000 per idea. Our risk management guide for funded traders shows how to size option positions from that number using the current exchange lot size.
5. Doubling down on losers
What happens: A NIFTY call is down ₹8,000. Instead of exiting, the trader buys more to "average". The position is now twice the size, and the next leg down costs twice as much. This is how a ₹8,000 loss becomes a closed account in one session.
The fix: Never add to a losing position. Decide your exit before entry, and only add to trades that are working, within your original risk budget.
6. Ignoring correlation
What happens: A trader buys NIFTY calls, BANKNIFTY calls and long HDFC Bank futures, believing these are three trades. They are effectively one bullish bet on large Indian banks and the index. A single negative headline hits all three at once.
The fix: Count correlated positions as one trade for risk purposes. If NIFTY, BANKNIFTY and heavyweight banking stocks point the same way, their combined worst case must fit your per-trade risk.
04Timing mistakes: the open, expiry and news
7. Trading the first 15 minutes blindly
What happens: The open between 09:15 and 09:30 IST is often the most volatile part of the session. Gaps, wide option spreads and sharp reversals catch traders who enter on the first candle without a plan.
The fix: Unless the opening is part of a tested strategy, wait for structure to form. Let the first fifteen minutes show direction before you commit risk.
8. Expiry-day option buying sprees
What happens: On expiry day, cheap out-of-the-money options look like easy multiples. A trader buys one, then another, then a third after the first two decay. Ten small trades add up to a large loss, and premium decay works against every one.
The fix: Cap the number of trades on expiry days, for example three. Size option buys so a full premium loss fits your per-trade risk. On funded accounts, new option positions opened in the last 30 minutes of expiry day are not counted for payout, so there is little reason to open them at all. Closing is always fine.
9. Trading inside news windows
What happens: RBI policy, the Union Budget and index-heavy results can move the index sharply in seconds. Traders who hold large positions into these events risk a gap through their daily floor. Separately, profit from trades opened within five minutes either side of a listed event is not counted for payout.
The fix: Check the event list on your dashboard each morning. Be flat or small before listed events, and avoid opening new trades in the ±5 minute window.
05Mindset mistakes: rushing the target
10. Rushing the target despite no time limit
What happens: Greenwick has no time limit on any plan, yet many traders behave as though they have a deadline. They size up near the target, or try to pass in the minimum 5 trading days. One oversized trade wipes out weeks of steady progress.
Picture a trader at ₹10,65,000 on a ₹10L Phase 1, with ₹15,000 left to the 8% target. Instead of taking the usual ₹6,000-risk trade, they take a ₹30,000-risk trade to finish today. It loses. They are now back at ₹10,35,000, frustrated, and the next decision is worse. Three calm days at normal size would have finished the phase.
A challenge with no deadline can only be rushed by the trader.
The fix: Keep risk per trade the same from the first rupee of profit to the last. If conditions are poor, do not trade. Revenge trading and target pressure are covered in our trading psychology guide.
06Hard-rule breaches traders overlook
11. Multi-account, hedging and copy-trading breaches
What happens: Some traders open two accounts and take opposite positions, so one is sure to pass. Others run accounts for friends, or connect a bot or copy service. These are hard rules: hedging across Greenwick accounts, one person running several accounts, and copy-trading or bots without written approval all close the account.
A fifth hard rule, platform abuse, covers exploiting price errors or delays in the simulation. Trades that rely on a glitch rather than a market view fall here. None of these rules is a technicality; each exists because the evaluation must measure your own trading skill.
The fix: Trade one account, yourself, with your own decisions. If you want more capital, pass and grow through scaling, which can add 25% to the account every four months when you meet the conditions.
12. Not reading the rulebook
What happens: Traders assume rules work like another platform they used. They do not know that MIS positions auto-close at 15:15 IST, that overnight NRML is only available where the plan allows, or which rules close an account versus only affect a payout.
Five hard rules close the account: breaching the daily loss floor, breaching the max loss floor, hedging or multiple accounts, unapproved copy-trading or bots, and platform abuse. Consistency, news windows and expiry-day timing never close an account; they only adjust or delay that payout.
The fix: Read the full rules page once before your first trade. Rules apply as they stood when you bought the account.
07Choosing the wrong plan or size
13. Picking a plan that does not suit your style
What happens: A trader with wide intraday swings buys a 1-Step, which has a tighter 3% daily limit, or an Instant account with a 2% daily limit and a trailing floor. Another buys a ₹50L account to "feel serious" and cannot size small enough to stay calm.
| Plan | Target | Daily loss | Max loss | Suits |
|---|---|---|---|---|
| 2-Step | 8% then 5% | 4% | 8% static | Traders who want the most room |
| 1-Step | 10% | 3% | 6% static | Consistent traders who want one phase |
| Instant | None | 2% | 5% trailing | Tight, experienced risk managers |
The fix: Match the daily limit to your normal worst day. Choose an account size where your usual trade fits comfortably. Compare fees on the pricing page and structures in challenge types.
08Prop firm mistakes at a glance
- Write floors in rupees before 09:15 IST
- Count open P&L as real loss
- Treat correlated positions as one trade
- Check the dashboard event list daily
- Use the absence of a time limit
- Averaging into losing options
- Expiry-day buying sprees
- Oversizing near the target
- Hedging across accounts or using unapproved bots
- Assuming the rules match another platform
If you recognise yourself in two or three of these, you are not unusual. Most traders do. The difference is fixing them before the next account, not after it. Our step-by-step guide on how to pass a prop firm challenge turns these fixes into a phase plan.
09Pre-trade checklist before every order
Run through this list before every entry. It takes under a minute and catches most of the mistakes above.
- Know today's floors
Daily floor and max loss floor in rupees, including the current trailing level on Instant.
- Check live equity
Booked plus open P&L. How much of today's limit is already used?
- Set rupee risk
Stop defined, size calculated so the loss fits your per-trade budget.
- Check correlation
Does this trade add to an existing bet on the same index or sector?
- Check the clock
Not in the first 15 minutes without a plan, not in a news window, not opening options in the last 30 minutes of expiry.
- Check your state
Is this in your written plan, or a reaction to the last trade?
Trading involves risk, and no checklist removes it. What it does is make sure every loss you take is one you planned for, which is how disciplined traders stay in the game long enough to pass.
