Overtrading and chasing losses
The lesson defines overtrading as taking more trades than your written plan allows. Chasing losses means increasing your position size after a loss to win the money back quickly. Both patterns often appear together. The worked example shows a day with thirty trades on USD/ZAR and separates the trading result from the cost of spread and commission.
Why the second trade feels urgent after the first one loses
A loss on USD/ZAR does not change the market. It changes how the next few minutes feel. The mind treats the lost rand as a debt, and a debt demands action. The chart in front of you suddenly looks like it holds the answer, even though nothing on it has moved in your favour by itself.
This is where overtrading starts. Your written plan might allow four trades a day. After a loss, four feels too slow. The hand reaches for the buy or sell button before the setup is complete. Each extra trade adds a spread cost, and the spread is charged whether the trade wins or loses.
The market does not know you lost. It has no memory of your last trade and no obligation to give the money back. Every new position is a fresh bet with its own cost. The only thing that has changed is your willingness to accept a worse setup.
If you take twenty trades on USD/ZAR at 0.10 lots and the spread is one pip, each trade costs R18.41 at a rate of 18.4100. Twenty trades cost R368.20 in spread alone. That cost is paid before any profit or loss on the price movement is counted.
How bigger size after a loss multiplies the cost, not the chance
Chasing losses means raising your position size after a loss to win the money back in one move. The logic feels simple: a bigger trade earns more per pip, so fewer pips are needed. The arithmetic is correct, but it cuts both ways. A bigger trade also loses more per pip, and the spread is charged at the larger size.
Suppose you normally trade 0.10 lots on USD/ZAR. After a R150 loss, you double to 0.20 lots. One pip now costs R36.82 in spread instead of R18.41. If the trade goes against you by ten pips, the loss is R368.20 before commission, not R184.10. The recovery target has grown while the account has shrunk.
The plan you wrote before the session was based on a size your account could survive. Doubling that size breaks the plan at the exact moment you are least able to judge a setup clearly. The market does not reward urgency. It charges for it.
A useful check is to write the rand cost of one pip at your normal size on a card. At 0.10 lots on USD/ZAR at 18.4100, that is R18.41. If you are about to trade at a size where you cannot state the pip cost without checking, you are outside your plan.
What the daily limits actually stop, and what they do not
A daily trade limit and a daily loss limit in rand are not predictions. They are circuit breakers. The trade limit stops the slow bleed of spread and commission. The loss limit stops the account from reaching a size where normal trading is no longer possible.
These limits do not stop you from having a bad day. They stop a bad day from becoming a bad week. If your plan allows four trades and a R200 loss limit, and you have taken four trades and lost R150, the lesson is to stop. The R150 is gone. Taking a fifth trade to recover it adds cost and breaks the rule you set when you were calm.
The urge to win it back will not disappear because you read this. It will arrive again. The only reliable response is a written next step: note the trade you would have taken, close the platform, and review the note at the next session. Most of those notes will show a setup you would not have taken in the morning.
Brokers differ in how they charge. Some add commission on top of the spread. Some widen the spread around news or at market open. Some round the pip value differently. The rand figures here are an example based on the numbers given, not a quote from any broker.
30 trades on USD/ZAR: where the money goes
| Step | Amount | Note |
|---|---|---|
| Planned trades for the day | 3 | From the reader's own trading plan |
| Actual trades taken | 30 | The reader traded ten times the plan |
| Spread cost per trade (0.10 lots) | R18.41 | USD/ZAR at 18.4100; 0.10 lots means 10,000 units. One pip is 0.0001. 10,000 × 0.0001 = 1 USD per pip. At 18.4100, 1 USD = R18.41. A spread of 1 pip costs R18.41. |
| Total spread cost for 30 trades | R552.30 | 30 × R18.41 = R552.30 |
| Gross trading result before costs | R120.00 | The sum of the 30 trades before any costs, as recorded by the reader |
| Net result after spread | -R432.30 | R120.00 − R552.30 = -R432.30 |
| Share of costs in the gross result | 460% | R552.30 ÷ R120.00 = 4.603, or 460% |
Your broker may charge commission on top of the spread, and the spread itself can widen around news or at market open. Some brokers round the pip value or quote a different spread for the same pair. The figures here are only an example based on the numbers given.
Doing it once, step by step
You will set two limits in rand before the session, then follow a fixed routine when either limit is reached. The order matters: write the limits first, trade only inside them, and stop when one is hit.
- 01
Write the daily trade limit
Decide how many trades your plan allows in one day. Write the number where you can see it while trading. This is the maximum, not a target. If your plan allows four, the fourth trade is the last one, win or lose.
- 02
Write the daily loss limit in rand
Convert your risk per trade into rand and multiply by the number of trades you allow. If you risk R50 per trade and allow four trades, the daily loss limit is R200. When the account is down R200 for the day, the session is over.
- 03
State the pip cost at your normal size
For USD/ZAR at 0.10 lots, one pip is 1 USD, which is R18.41 at 18.4100. Write that figure down. If you cannot say the pip cost at your current size without checking, you have already left your plan.
- 04
Stop when either limit is reached
When you have taken your allowed number of trades or lost your rand limit, close the platform. Do not open another position to recover the loss. The spread and commission on the next trade are charged regardless of the outcome.
- 05
Record the trade you wanted to take
If the urge to win it back is strong, write down the trade you would have taken: the pair, the direction, the size, and the reason. Do not place it. Review the note at the next session and compare it with your plan.
- 06
Review the week, not the day
At the end of the week, add up your spread and commission costs in rand. Compare that total with your gross result. If costs are a large share of gross, the problem is trade count, not market direction.
The mistake most people make here
The common mistake is to treat a loss as a signal to trade more and larger, hoping one big win will fix the day. That raises both the number of trades and the cost per trade, so the spread and commission grow faster than any likely gain. Instead, set a daily trade limit and a daily loss limit in rand before you start. When either limit is hit, stop for the day. If you feel the urge to win it back, write down the next trade you would take and wait until the next session to review it.Check yourself
If you take 20 trades on USD/ZAR at 0.10 lots and the spread is 1 pip, what is the total spread cost in rand? Use USD/ZAR at 18.4100.
One pip at 0.10 lots is 1 USD. At 18.4100, that is R18.41. 20 trades × R18.41 = R368.20.
Your gross result before costs is R80.00 and you paid R368.20 in spread. What is the net result, and what percentage of the gross result did costs take?
Net result: R80.00 − R368.20 = -R288.20. Costs as a share of gross: R368.20 ÷ R80.00 = 4.6025, or about 460%.
Your plan allows 4 trades a day. You have taken 4 and lost R150. What should you do next according to this lesson?
Stop trading for the day. You have reached your planned trade count. Taking more trades to recover the R150 is chasing losses and will add more spread and commission costs.
Questions that come up next
1. My plan allows four trades a day. I took four and lost R150. What do I do next
Stop trading for the day. You have reached the trade count your plan allows, so the next trade is overtrading by definition. Taking more trades to win back the R150 is chasing losses, and every extra trade adds spread and commission. Write down any setup you think you see and review it at the next session. The market will still be there tomorrow.
2. If I lose R150 on one trade, how much must the next trade make to get back to where I started
More than R150, because the recovery trade pays its own spread and commission. At 0.10 lots on USD/ZAR, one pip costs R18.41, so the price must move in your favour by enough to cover R150 plus that cost. If you double the size to 0.20 lots, one pip costs R36.82 and the same ten-pip move against you loses R368.20. The target grows at the same time as the risk.
3. Does a bigger position size make it more likely that I win the money back
No. A bigger size changes the rand value of each pip, not the chance that the price moves your way. It raises the amount you gain per pip and the amount you lose per pip by the same factor. The spread is also charged at the larger size, so the cost of entering and exiting rises. Risk grows faster than any likely gain.
4. I trade on my phone and the spread looks different from the figure in this lesson. Why
The spread varies between brokers and between accounts at the same broker. It can also widen around news releases, at market open, and when the market is quiet. Some brokers round the pip value or quote USD/ZAR with more decimal places. The R18.41 figure comes only from the numbers used here: 0.10 lots, one pip, and a rate of 18.4100.
5. Can I set a daily loss limit in rand if I do not know my pip cost
You can, but you need the pip cost first. Write the rand value of one pip at your normal size on a card and keep it beside you. At 0.10 lots on USD/ZAR at 18.4100, that is R18.41. Then a limit of, say, R200 is about eleven pips against you at that size. Without the pip cost, a rand limit is only a number.
6. The urge to win the money back is strong. Is there anything to do in the moment
Write down the trade you want to take, with the entry, the size and the reason, and then wait. Review it at the next session, when the loss is no longer fresh. Most of these notes do not look like good trades the following day. This keeps the decision in your plan rather than in the feeling.
The words used on this page
- Overtrading
- Taking more trades than your written plan allows. It usually starts after a loss, when four trades a day feels too slow. Each extra trade adds a spread cost whether it wins or loses.
- Chasing losses
- Raising your position size after a loss to win the money back quickly. The rand value of each pip rises, so both the gain and the loss per pip grow. The spread is charged at the larger size too.
- Spread
- The gap between the buy price and the sell price on USD/ZAR. It is charged when you open a trade and again in effect when you close it. At 0.10 lots and a rate of 18.4100, one pip of spread is R18.41.
- Pip
- A small step in the price of a currency pair. On USD/ZAR, one pip is 0.0001. The rand value of one pip depends on your position size, so 0.10 lots gives R18.41 per pip at 18.4100.
- Daily loss limit
- A rand amount you set before the session as the most you will lose that day. When it is reached, you stop trading until the next session. It works only if the figure is written down before you start.
- Commission
- A separate charge some brokers add on top of the spread. It varies between brokers, and some accounts do not charge it at all. Check your own account terms rather than assuming a figure.
What to take away
- A loss does not change the market, only how the next few minutes feel. The market has no memory of your last trade and no obligation to return the rand.
- Overtrading adds spread cost with every extra trade. At 0.10 lots on USD/ZAR, twenty trades cost R368.20 in spread before any price movement is counted.
- Doubling size after a loss doubles the pip cost, from R18.41 to R36.82 at 0.20 lots. It does not improve the chance that the price moves your way.
- Set a daily trade limit and a daily loss limit in rand before you start. When either is reached, stop for the day and review any notes at the next session.
