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.
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."
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.
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.
