Weekly Loss Limits and Profit Targets
Add a second layer of protection that tracks cumulative P&L across the entire trading week.
6 min read
Daily loss limits protect you from a single bad day. Weekly loss limits protect you from a string of bad days that individually stay under the daily threshold but collectively erode your account. Many prop firms enforce weekly drawdown rules in addition to daily limits, and MimikTrader lets you mirror those rules directly on each follower account.
How Weekly Limits Differ from Daily
Daily limits track P&L within a single trading session (midnight to midnight, reset at 5 PM CT each day). Weekly limits track cumulative P&L across the entire trading week, from Sunday evening through Friday afternoon. The key differences are:
- Accumulation: Daily P&L is added to the weekly total at the end of each trading day. If you lose $400 on Monday, $300 on Tuesday, and $200 on Wednesday, your weekly P&L is -$900 even though no single day exceeded a typical daily limit.
- Reset timing: Daily limits reset every day at 5 PM CT. Weekly limits reset once per week on Sunday at 5 PM CT, which aligns with the CME Globex weekly session open.
- Lock behavior: When a weekly limit is breached, the account is locked with a weekly lock reason. This lock persists through daily resets — the daily reset at 5 PM CT does not unlock a weekly-locked account.
- Opt-in: Weekly limits are disabled by default. You must explicitly enable them per follower account on the Risk Management page.
The Accumulation Logic
Understanding how daily P&L rolls into weekly P&L is critical to avoiding surprises. Here is the exact sequence that runs at 5 PM CT each trading day:
- 1
Snapshot start-of-day balances
MimikTrader records the current balance of every trading account as the new start-of-day reference point for the next session. - 2
Accumulate daily P&L into weekly total
For every account with a risk profile, the current day's P&L is added to the running weekly total. If the account's daily P&L is-$500and the weekly P&L was already-$1,200, the new weekly P&L becomes-$1,700. - 3
Reset daily counters
Daily trade count is zeroed out, daily P&L on trading accounts is reset to zero, and accounts locked by daily risk breaches are automatically unlocked. - 4
Weekly-locked accounts stay locked
Accounts that were locked due to a weekly limit breach are not affected by the daily reset. They remain locked until the weekly reset on Sunday.
Weekly Reset on Sunday
Every Sunday at 5 PM CT, MimikTrader performs a weekly reset. This coincides with the CME Globex weekly session open when futures markets reopen for the new trading week. During the weekly reset:
- All weekly P&L totals across every risk profile are reset to zero.
- Accounts that were locked specifically by a weekly risk breach are automatically unlocked and their status returns to OK.
- Accounts locked by daily breaches, manual locks, or trailing drawdown breaches are not affected by the weekly reset.
After the weekly reset, the accumulation cycle begins again. Monday's daily P&L will be the first entry added to the new week's running total.
Configuring Weekly Limits
Weekly limits are configured per follower account on the Risk Management page. There are two independent settings, each with its own enable toggle:
Weekly Loss Limit
This is the maximum cumulative loss allowed across the trading week. Enter it as a positive dollar value. If your prop firm allows a maximum weekly loss of $2,000, enter 2000. When the weekly P&L drops to or below the negative of this value, the account transitions to LIQUIDATE_ONLY mode, open positions are flattened, and the account is then locked.
Weekly Profit Target
This is an optional cap on weekly profits. Some traders use this to lock in gains and prevent overtrading after a strong week. When the weekly P&L reaches or exceeds this value, the account is locked for the remainder of the week. It unlocks automatically at the Sunday reset.
Real-Time Enforcement
Weekly limits are enforced in two places within the MimikTrader risk engine:
- At trade time: When a new leader fill arrives, the risk manager checks the follower's weekly P&L against its weekly loss limit and profit target before allowing the trade through.
- On every price tick: The real-time risk monitor continuously recalculates the effective weekly P&L (accumulated weekly total plus current unrealized P&L) and triggers an auto-flatten if the limit is breached mid-trade.
This dual enforcement means that even if a trade was opened within limits, a market move against you can trigger the weekly limit breach during the trade. The tick-level monitor ensures the account is protected in real time, not just at order entry.
Example Weekly Scenario
Here is a complete week showing how daily P&L accumulates into the weekly total for a follower with a $2,000 weekly loss limit:
- Monday: Day P&L = -$400. Weekly total = -$400. Status: OK.
- Tuesday: Day P&L = +$200. Weekly total = -$200. Status: OK.
- Wednesday: Day P&L = -$800. Weekly total = -$1,000. Status: OK.
- Thursday: Day P&L = -$600. Weekly total = -$1,600. Status: OK.
- Friday: Day P&L starts at $0. An open trade moves against you by $500 in unrealized loss. The effective weekly P&L is now -$2,100, breaching the -$2,000 limit. The account is auto-flattened and locked with a weekly lock.
The account remains locked through Saturday and is automatically unlocked at the Sunday 5 PM CT weekly reset.
