Risk per trade: sizing stakes as a percentage of your balance

Risk per trade is the share of your balance you are prepared to lose on a single trade. On a Higher/Lower trade this is easy to measure, because the stake is the maximum loss: a $10 stake on a $500 balance is 2% risk, no more and no less. The point of choosing that percentage in advance is simple: it decides how many bad trades in a row you can survive, and losing streaks are a certainty, not a possibility.

Stake = risk, which makes sizing simple

In many kinds of trading you calculate risk from a stop-loss distance. Here you do not need to. If the trade loses, the whole stake goes; if it wins, you receive the stake plus the payout. So position sizing reduces to one line:

Stake = balance × risk percentage

Most risk guidance for active traders lands somewhere between 1% and 2% per trade. This is a widely used convention, not a law of nature. It exists because small percentages keep any single trade, and any realistic streak, from doing serious damage. Some traders use less. Very few who use much more last long.

Example stake table

The minimum stake on Sky Trade is $1. That sets a practical floor: with a $50 balance, the smallest possible trade is already 2% of it. If your balance is so small that even the minimum stake is a large percentage, that is useful information in itself. The risk calculator does this arithmetic for any balance.

Why the percentage matters: streaks

Because the payout is below 100%, even a trader who is right more often than not will hit long losing runs. With roughly 50/50 outcomes, a run of 7 or more losses in a row is more likely than not somewhere in 200 trades. The question is not whether a streak arrives but what it does to you.

If you recalculate the stake from the current balance after each trade, this is how many consecutive losses it takes to lose a quarter and half of your balance:

At 1–2%, a bad run is unpleasant but survivable, and you still have the capital and the composure to review what went wrong. At 10%, an ordinary streak cuts the account by two thirds. What it then takes to recover is covered in drawdown and recovery.

Fixed percentage, not fixed feelings

The most common sizing mistake is not choosing 5% instead of 2%. It is letting the stake change with mood: bigger after a win because you feel sharp, bigger after a loss because you want it back. Stakes that rise after losses turn a normal streak into a disaster; the extreme version of this is described in why martingale fails.

Choose the percentage once, write it into your plan, and change it only at a scheduled review, not in the middle of a session.

A maximum daily loss: your own circuit breaker

Sky Trade has no built-in daily loss limit. The platform will let you keep trading until your balance runs out, so a daily stop is your own discipline, set before you start.

A simple version:

• Daily loss limit as a percentage of the starting balance, for example 5–6%.
• Daily trade limit, for example 15–20 trades.
• Whichever comes first ends the session. No exceptions for "one more setup".

The terminal settings can help a little: turning on confirmation for large trades adds a pause before an unusually large stake, which is often the moment a plan gets broken.

Worked example

Illustrative numbers: your real balance is $400, risk per trade is 2% ($8, kept fixed for the day), and your daily loss limit is 6% ($24).

1. First trade: loss. Balance $392.
2. Second trade: win at 85%, +$6.80. Balance $398.80.
3. Third and fourth trades: losses. Balance $382.80.
4. Fifth trade: loss. Balance $374.80. You are now down $25.20 from the starting $400, past your $24 limit.

You stop for the day. Tomorrow's stake is 2% of $374.80, about $7.50. The streak cost about 6% of the account instead of the much larger hole that "doubling to win it back" would have dug.

What sizing cannot do

Position sizing controls how fast you can lose; it does not change whether a trade wins. If your win rate is below the break-even rate for your payouts, small stakes only make the losses slower. For the underlying maths see why most beginners lose.
