Take-profit & re-entry calculator

Enter your average buy price and quantity — you instantly see the prices where T1, T2 and T3 sells fire, how much profit you park in stablecoins, and at which prices the re-entry buys happen if the price then falls. Same engine as the diary; nothing leaves your browser.

Sell 50% when price doubles, then 20% of the remainder each further doubling. A tail always remains. Buy the dip from parked funds, aiming to rebuild double the opening amount. Riskiest: buys more as price falls.

T1 sells 50%, every further level 20% of what is left — so part of the position always remains (a tail for a big run).

If the price falls after T1 (€200)

At the start of the fall you hold 5 units and €1,000 of parked stablecoins. Re-entry buys only from this pool — no new capital needed.

After the buy-backs you hold 20 units (×2 of the original), average €75, €0 left in the pool.

"Rebuild to 2×" is martingale-like: it buys more as the price falls. If the price never recovers, the parked profit is at risk too.

Closed system: buy-backs are funded only by this position's parked profit. This is a rule calculation — not a forecast and not advice.

FAQ

What are T1, T2 and T3?
They are take-profit levels. The default strategy puts T1 at +100% from your average price (the price doubles) and sells half the position there — you take your initial capital back. T2 and T3 are each further doubling, where 20% of the remainder is sold so a part always stays.
What is re-entry (buying back)?
When the price falls hard after you took profit, part of the parked stablecoins buys the same token back cheaper. Default: at −50% from the T1 price half the pool is spent, at −75% the rest, aiming for 2× the original quantity.
Do I need new money to buy back?
No. The strategy is a closed system: buy-backs are funded only by the same position's realized profit. If the pool is not enough, it buys what it can — the calculator shows this.
Is this investment advice?
No. The calculator only applies the rules you chose to the numbers. Crypto assets are highly risky and no profit is guaranteed. Selling into a stablecoin can be a taxable event in many countries.
