Block trading on specific days of the week — automatically. No Thursdays on expiry. No Mondays after a bad week. No Fridays before a long weekend. Your schedule, enforced by software.
Every experienced F&O trader has days they know they should not trade — but they do it anyway. The day-based kill switch removes the decision from your hands entirely. Select the days of the week you do NOT want to trade, and TradeGuard automatically blocks any trading on those days — account locks at market open and stays locked all day.
WHICH DAYS DO TRADERS AVOID?
MON
Gap risk from weekend news
TUE
Often quiet, low conviction
WED
Nifty expiry (NSE changes vary)
THU
BankNifty expiry — most dangerous for buyers
FRI
Pre-weekend position risk
Thursday: The Most Dangerous Day for Retail Traders
BankNifty weekly expiry falls on Thursday. Nifty also has expiry cycles that create extreme volatility. Near-the-money options on expiry day can move 500–2000% in minutes — and reverse just as fast. Most retail options buyers lose the most money on Thursday, not because they're wrong about direction, but because time decay accelerates exponentially in the final hours.
Many professional traders simply block all trading on expiry Thursdays and only sell premium rather than buy it. The day-based kill switch makes this policy automatic — no temptation, no "just this one trade."
Monday Gap Risk
Weekend news creates gaps at Monday open. Global markets move over the weekend — US markets close Friday night, Europe opens Monday morning, and Indian markets open with a significant gap risk. If your strategy doesn't account for this, Mondays are dangerous.
Thursday 9:15 AM — DAY RULE ACTIVE (Thursday blocked)
Account locked all day. BankNifty expires with 200pt move.
Other accounts blow up chasing the spike. Yours is protected.
Friday — trading resumes normally at 9:15 AM.
STRATEGY-BASED DAY SELECTION
Analyse your own trade history to identify which days are consistently bad for you. Pull your broker's trade history for the last 3–6 months and sort by day of week. Most traders find 1–2 specific days that account for the majority of their losses. Block those days in TradeGuard.
You can also use the day rule to enforce a trading schedule: for example, only trading Tuesday through Thursday when market conditions are typically more predictable after Monday's gap settling and before Friday's pre-weekend positioning.

FAQ
Yes — you can select as many days as you want to block. Block just Thursday, or block Thursday and Monday, or trade only on Tuesday-Wednesday-Thursday. The rule applies every week automatically.
If the market is closed, the rule simply has no effect — there's nothing to block. The rule only activates on market trading days.
You can modify rules for the upcoming week after 3:30 PM on Friday. Rules cannot be changed during active market hours — this is intentional to prevent circumventing the rule when you're tempted to trade.
Yes. The day rule blocks recurring days every week (e.g., always block Thursday). The specific date trading lock blocks individual calendar dates — e.g., block June 7, 2026 for RBI policy day. Use both together for complete coverage.
