Sizing up after two wins: where the damage actually comes from

Support sees a version of the same message a few times a month: a member has been following the signals for two or three weeks, doing well, and one stop wiped out the run. The stop was normal. The size was not. The story below is assembled from several of those threads, with the numbers changed; it is an illustration, not one member's account.

The pattern

Week one at 0.02 lots. Two targets hit, then three. The account is up 4%, which is small in money and enormous in confidence. Week two at 0.05, because it is "working". Two more wins. Week three, a gold signal, 0.15 lots, because the last five were fine and gold moves. The stop hits. At 0.15 lots gold, an 80-pip stop is $120, and the account was $900. Thirteen percent, from one ordinary stop, on a week when the signals did nothing unusual.

The signals had the same stop rate all month. The member had the same stop rate all month. The only variable that changed was the number typed in the lot field, and it changed in exactly the wrong direction: smallest when the trades were winning, largest when the stop arrived. It arrives eventually for everyone.

Why it happens

Two wins in a row feel like information. They feel like the service is hot, or that you have found the rhythm, or that the risk was overstated. None of that is true. Two wins in a row, on a desk where most signals reach their first target, are the most ordinary event there is; they contain no information about the third trade at all. But the feeling of information is strong, and it points in one direction: bigger.

The stop, when it comes, is then interpreted the same way. "It was working until I sized up" becomes "I jinxed it", which becomes either sizing back down (fine) or doubling again to recover (the losing streak guide covers where that goes).

What it costs

Take any month from the results page. At a fixed 1% per trade, every stop costs 1% and every winner returns what its own target and stop distance say, a per-trade sum the results page guide shows how to do. The point here is not the month's total; it is what a drifting size does to any total.

Now let the size drift the way it does in practice: 1% for the first ten signals, 2% after a good run, 3% on a gold signal that "looks strong", back to 1% after the stop. Same signals, same outcomes. The stop is no more likely after a run than before it; what changes is that when it lands on a 3% trade it costs three times what the plan allowed, and the trades sized at 3% are exactly the ones taken after a run. The wins were banked small and the loss is taken large. A member who does this can turn a month the record shows as up into a flat or losing one without ever taking a trade the desk did not post.

The one rule

Risk per trade is a percentage you set once, away from the screen, and leave alone. The lot size changes on every signal because the balance and the stop distance change; the percentage does not, and it has no input for how the last trade went. The position sizing guide has the formula.

Ways to make the rule hard to break:

• Risk % mode on the copier. The copier recalculates every trade from the balance and the signal's stop. There is no lot field to type in at the top of a run.
• Write the size next to the signal, before the entry. In a journal. If the number in the journal and the number on the platform differ, you have caught yourself.
• Grow size with the balance, on a schedule. The account at $1,200 can risk 1% of $1,200. That is the only size increase that exists. Monthly, from the formula, never on a Thursday afternoon.

The same month at a fixed size

Run that opening story again with the size set by the rule instead of the mood: 1% of the current balance on every signal, divided by that signal's stop distance and pip value, rounded down to the broker's lot step, exactly as the position sizing guide sets it out. The lot size changes with every signal; the percentage does not. The gold stop that cost 13% now costs whatever the rounded lot size makes it, inside the chosen budget before costs: on a $900 account with an 80-pip stop, 1% gives 0.011 lots, rounded down to 0.01, an $8 planned loss, about 0.9%. The two good weeks are the same two good weeks. Whether the month ends up depends on what the signals did, which a fixed size cannot change; what it can change is that a normal stop is a normal stop, and the message to support never gets written. That is the whole of what the rule does, and it is why it is the one rule we would ask a new member to keep before any other.
