Position size calculator for memecoin trades¶
A position size calculator for memecoin trades: enter the share of your wallet you can lose and your stop loss, and get the buy size in SOL that fits both.
Most blown wallets were not one bad token. They were one bad size. The size is the only part of a memecoin trade you fully control, so decide it with a sum and not with a feeling.
Try the size with play SOL first: paper trading memecoins.

How to use the position size calculator¶
- Trading wallet is the SOL you trade with, not everything you own.
- Most you will lose on one trade is your call. It is the share of the wallet that goes if the trade hits its stop.
- Stop loss is how far below your entry you get out. In clusterz a stop loss can sit anywhere from 1% to 95%.
- Extra loss if the stop fills late covers the gap between your level and the real fill. On a thin pool a big sell can take the price through your stop before your own sell lands.
The Buy size is the answer: put in more than that and a stopped trade costs more than you said you would lose.

How position sizing works¶
The sum is short:
Buy size = wallet × share you will lose ÷ (stop loss + late fill)
A 10 SOL wallet, 2% at risk, a 30% stop and 5% for a late fill: 10 × 0.02 ÷ 0.35 = 0.57 SOL. If the stop fills where the sum expects, you lose 0.2 SOL, which is 2% of the wallet.
Two things follow from it:
- A tighter stop allows a bigger buy, and gets hit more often. Memecoins swing 30% on nothing.
- A wider stop needs a smaller buy. Halve the buy when you double the stop and the SOL at risk stays the same.
Position size by risk and stop loss¶
A 10 SOL wallet, no allowance for a late fill:
| Share of wallet at risk | Stop loss 20% | Stop loss 30% | Stop loss 50% |
|---|---|---|---|
| 1% (0.1 SOL) | 0.5 SOL | 0.33 SOL | 0.2 SOL |
| 2% (0.2 SOL) | 1 SOL | 0.67 SOL | 0.4 SOL |
| 5% (0.5 SOL) | 2.5 SOL | 1.67 SOL | 1 SOL |
And what a losing streak does, if every trade loses the same share of what is left:
| Share of wallet lost per trade | Losing trades in a row that halve the wallet |
|---|---|
| 1% | 69 |
| 2% | 35 |
| 5% | 14 |
| 10% | 7 |
Seven bad trades in a row is an ordinary week in the trenches. That is the whole argument for small sizes.
What the calculator leaves out¶
- A stop is not a guarantee. It sells at the market once the price reaches your level. If the pool drops 60% in one move, your 30% stop fills near 60%. The late-fill box is a guess at that, not a limit on it.
- Rugs. When the pool is emptied there is nothing to sell into at any level. The only protection against that is the size.
- No stop at all. Without one, the SOL at risk is the whole buy, and the buy size is simply the SOL you said you could lose.
- Fees. Every trade pays the pool and the app on the way in and out. The profit calculator shows what that costs.
- Several positions at once. Five open trades at 2% each is 10% of the wallet at risk at the same moment, and memecoins tend to fall together.
None of this is advice on how much to risk. It is the sum that turns your number into a buy size.
Where to set size and stops in clusterz¶
- Buy presets in Trade settings hold your four buy amounts. Put the size from this page there once, so a one-tap buy is already the right size. Every other setting: Settings explained.
- Exits for new buys puts the same stop loss on every token you buy yourself, so the stop is there before you need it. See Set exits for new buys.
- The Automatic stop loss is a protection rule that sells all at -50%, wider when a token swings hard, never past -80%. It is a switch, off until you turn it on. See Steps and protection.
- A copy has its own size and a daily loss limit, which stops it buying for the day once sold positions have lost that much. See Copy Trade.
- Try a size in Practice first. Play money, live market, same stops.
Position sizing FAQ¶
How much should I put into one memecoin trade?¶
Only you can set the share of your wallet you can lose on a trade. Once you have that number and a stop loss, the buy size is arithmetic: wallet times the share at risk, divided by the stop loss. The calculator above does it.
What is the 1% rule in trading?¶
A common rule of thumb: size every trade so that hitting your stop costs about 1% of your trading wallet. It is a way to survive long losing streaks, not a promise of profit. At 1% it takes 69 losing trades in a row to halve a wallet.
Does a stop loss limit my loss on a memecoin?¶
It limits it when there are buyers at your level. A stop sells at the market once the price reaches it, so on a thin pool or a sudden drop the fill can land well below the level. If the pool is drained, nothing sells.
Should position size change with the size of the pool?¶
Yes. A buy that is large next to the pool moves the price against you on the way in and again on the way out. The smaller the pool, the smaller the size that can get out near the price you see.
