Overtrading and chasing losses

A trader closes a long position on USD/INR at 83.2500 with a loss of ₹2,000. The plan for the day allowed two more entries. Instead the next order goes in at double the usual size, 0.20 lots, on the reasoning that a single good move will erase the loss. One pip on 0.20 lots is ₹20, so the position now needs a move of 100 pips in the right direction just to recover the ₹2,000. The same 100 pips on the original 0.10 lots would have produced only ₹1,000.

Doubling the size does not double the chance of winning. It doubles the amount that each pip moves the account, in both directions. If the second trade also loses 50 pips, the loss on it is 50 x ₹20 = ₹1,000, and the day now stands at ₹3,000 down. A third attempt at 0.40 lots would risk ₹40 per pip, and a 50 pip loss there costs ₹2,000. Three ordinary losing trades, none of them large in pips, have produced a ₹5,000 drawdown.

The spread is charged on every one of those entries. At an average of 2 pips, the three trades cost 2 x ₹20 + 2 x ₹40 + 2 x ₹10 = ₹140 in spread alone, on top of the losses. The broker's charge is fixed per trade, so the only way to reduce it is to trade less. Raising size raises the spread cost in exact proportion.

A useful check before any recovery trade is to write down the pip distance required to get back to flat. If the answer is a move the market rarely makes in a day, the trade is not a recovery, it is a second bet on the same opinion.

Suppose a plan allows three trades a day and the average cost per trade, spread included, is ₹15. Three trades cost ₹45. A trader who takes twelve trades pays ₹180, and the nine extra trades are the difference: 9 x ₹15 = ₹135. None of those nine trades needs to be large to do damage. The cost is in the count.

There is a second cost that does not appear on the contract note. Each extra trade is a fresh decision, and decisions made in the middle of a losing session are made with less patience than decisions made before it. A trader who has already broken the three-trade limit once has set a precedent for the rest of the day. The limit is not a target to be reached; it is a ceiling that protects the account from the version of the trader who appears after two losses.

The daily limit works only if it is set in two units at once: a rupee figure and a number of trades. A rupee limit alone can be met by taking many small trades, which still pays the spread many times. A trade-count limit alone can be met by taking a few very large trades. Both limits together close the two routes by which a bad day becomes a bad week.

When either limit is reached, the session ends. Closing the platform is the simplest way to enforce it. The next decision is then made the following morning, with the full day's information and none of the day's emotion.

A day closes with a net loss of ₹4,000, of which ₹500 was spread. The spread is ₹500 ÷ ₹4,000 = 0.125, or 12.5% of the loss. That figure is worth calculating because it separates two different problems. A high spread share means the day was chopped up into too many trades. A low spread share means the trades were few but the direction was wrong, which is a question about the method rather than about discipline.

The remaining ₹3,500 came from price movement against the positions. That number is the one to compare with the plan. If the plan risked ₹1,000 per trade and the day lost ₹3,500, then three or four planned losses occurred, which is within the range any method produces. If the plan risked ₹1,000 and the day lost ₹4,000 on one trade, the size was wrong, not the method.

Neither figure tells the reader what to do next. The purpose of the review is to name which of the two habits was present, not to find a trade that will undo the result. A loss that is understood as a cost of doing business is easier to leave alone than a loss that is understood as a debt.

Brokers vary in how they quote and round spreads, and some charge commission on top. The split between spread and price movement will therefore differ between accounts. The contract note holds the figures that applied to the trades actually taken, and it is the only record worth reviewing.
