Loss response versus a precommitted trading process
Editorial. The hour after a loss tests whether entry, exit and standing aside still form one procedure. If size can expand, a loser can be held for hope, or a winner can be cut to soothe fear, recovery impulse has already bypassed the ruin and drawdown filters.
- A loss can start a negative loop in which later trades become riskier in an attempt to recover rather than tighter on the downside.
- Profit and loss exits set before entry keep the close inside the same procedure as the open, and a session is scored more by rule adherence than by that session's profit and loss.
- Each name and each added increment is judged on its own risk and reward; a gain elsewhere is not accepted as a reason to stay in a loser.
- After a losing stretch, cutting size into a comfort range is described as the way to take the next signal without freeze or revenge sizing.
The hour after a loss
Editorial. The hour after a loss is a systems test. The question is whether the trading-psychology-process is still one procedure that converts rule inputs, market state, and execution constraints into an entry, an exit, or a decision to stand aside over the system's holding period.
Editorial. If size can expand, a loser can be held for hope, or a winner can be cut to soothe fear, the entry-exit-abstention loop is no longer one testable procedure. Recovery impulse has replaced the original rules.
When recovery replaces the rules
A loss can start a negative loop in which later trades become riskier in an attempt to recover rather than tighter on the downside.
Holding a losing position past a reasonable point in hope of a rebound can deepen both the capital loss and the loss of confidence while blocking reallocation of funds.
After a reverse that feels like a whip, emotion can push a fast profit-take and an early exit from a still-working long because of fear of another decline.
Exits chosen at the open
A precommitted-exit sets profit and loss levels at entry so the close is produced by the same procedure as the open.
The working process sets both a profit-based exit and a loss-based exit before entry, and scores a session more by rule adherence than by that session's profit and loss.
Review each name on its own
Position-level-review judges each name on its own. Profit in one name is not accepted as a reason to stay in another, and the risk-reward ratio is recalculated on every increment.
Each add is treated as a fresh risk-reward increment. Larger size and longer time in a volatile or illiquid market are described as higher risk, not extra luck.
The process enlarges names that are working and drops names that are not, instead of chopping in and out and paying extra slippage and commissions.
Bounds that stay in force
Risk-of-ruin is a filter applied before entry and while a position is open. It bounds loss from equity, volatility, stop distance, and exposure so a recovery sequence cannot exhaust the account.
A drawdown-limit is a bound on equity decline that must stay in force before a new trade and throughout the hold, blocking larger size or later exits after a losing stretch.
The largest damage is associated with one-sided-concentration, being too heavy on one side of the market. A diversity of ideas is used as a control rather than a hedge invented for its own sake.
A string of losses can freeze action. Size-reset shrinks trade size into a comfort range so the next signal can be taken without freeze or revenge sizing.
Keeping capital intact and preferring ideas with limited downside is presented as what lets a trader return and operate again.
