Position Sizing in Crypto Trading: How Much to Risk on Each Trade

Position sizing is the decision about how large each trade should be, and it matters more than most traders expect. A good entry can be undone by a position that is too large, while a modest position can survive a run of bad trades.

What Position Sizing Means

Position sizing is choosing how much money to put into a trade, based on how much you are willing to lose if it goes wrong. It turns the vague question of "how much should I trade?" into a number you can calculate before you place the order.

Start With a Risk Limit

Many traders set a maximum percentage of their account to risk on any single trade, often a small figure such as 1% or 2%. The exact number is a personal choice, but having one stops a single loss from doing serious damage to your balance.

A Worked Example

Say your account holds $5,000 and you decide to risk 1% per trade, which is $50. You plan to buy a coin at $100 and exit if it falls to $95, so each unit risks $5. Dividing $50 by $5 gives 10 units, which is a $1,000 position. If the price hits your exit, you lose about $50, which is 1% of the account, even though the position itself is much larger.

Why the Exit Point Comes First

The size depends on where you would exit, so decide that first. A tighter exit allows a larger position for the same risk, and a wider one calls for a smaller position. Choose the exit based on the market, not on the size you would like to trade.

How Leverage Changes the Picture

Leverage lets you control a larger position with less margin, but it does not change how much you are risking on the trade. If you size by risk, as above, leverage only changes how much margin you need. Using high leverage with a large position can put the liquidation price very close to your entry. Bitval offers margin trading and futures markets, and displays the liquidation price on its futures interface.

Don't Forget Costs

Fees and slippage reduce your result on every trade. On Bitval, spot fees are 0.12% maker and 0.145% taker, and futures fees are 0.03% maker and 0.06% taker. On a small risk limit, these costs are a real share of what you stand to make.

Common Mistakes

• Sizing by how confident you feel instead of by the risk
• Increasing size after a loss to win it back
• Moving the exit further away so a losing trade can stay open
• Taking several correlated positions that fall together

A Simple Habit

Before every trade, write down the amount you will risk, the exit point and the resulting size. It takes a minute, and it makes your decisions consistent.

You can create a Bitval account to apply this to live spot and futures markets.
