Construct the stay-or-flatten decision before entry
Exit choices come after a position is already open, so fear and greed make them harder to carry out than unused entries. Exit construction writes a stop-loss, a time stop, and a trailing exit before entry so stay, scale, and flatten actions form one testable procedure.
- Exit choices are made after a position is already open, so fear and greed make them harder to carry out than unused entries.
- A skipped entry is only a missed chance, while a skipped exit can shrink the trading account.
- A constructed exit is expected to bound losing trades promptly while still leaving room for favorable trades to develop.
- Exit timing should be decided before entry, because leaving too soon can forgo remaining favorable movement and staying too long can turn gains into losses.
Why exits are harder than unused entries
Exit choices are made after a position is already open, so fear and greed make them harder to carry out than unused entries. A skipped entry is only a missed chance, while a skipped exit can shrink the trading account.
What exit construction is for
Exit construction is the work of choosing and combining leave rules before entry so stay, scale, and flatten actions form one testable procedure. A constructed exit is expected to bound losing trades promptly while still leaving room for favorable trades to develop.
A more complete exit design uses several exit types fitted to the current market setting and the trader's risk tolerance.
A stop-loss, a time stop, and a trailing exit
A stop-loss is a standing adverse-move limit, usually set as a maximum acceptable loss, that remains in force for the life of the position. A money-management stop-loss stays in force for the life of the trade and closes at a stated amount of adverse movement, though gaps or limit moves can produce a larger loss than that amount. Stops set too close tend to exit too often, while stops set too far accept extra loss.
A time stop is a calendar or bar-count limit that closes the position after a stated number of bars or days, whether the trade is ahead or behind.
A trailing exit is an adjustable protective level moved with a favorable trend so a reversal can flatten the position while keeping part of the unrealized gain.
Decide exit timing before entry
The stay-or-flatten decision is the daily choice, once a position is open, to keep the trade or close it under the prewritten exit rules. Exit timing should be decided before entry, because leaving too soon can forgo remaining favorable movement and staying too long can turn gains into losses.
