Pyramiding Calculator

Pyramiding means adding to an existing profitable position as price moves in your favour. Instead of buying your full intended position at once, you start with a base tranche and add smaller tranches each time the stock rises a set percentage. Done with an upright (decreasing-size) structure, the blended average entry stays well below the current price, leaving a cushion between your cost basis and the market — you only add to winning trades, never to losing ones.

Blended average entry is the quantity-weighted mean of all your entry prices: sum each tranche’s (shares × price), then divide by total shares. For example, 100 shares at $100 and 50 shares at $110 gives (10,000 + 5,500) / 150 = $103.33. This is the same as the average-price formula — each tranche is simply a lot in the weighted average.

Each new tranche is entered at a higher price but keeps the same fixed stop below. The combined position now has more shares, each at risk of falling back to that same stop. Total risk = total shares × (blended average − stop). Even with a decreasing (halving) scheme, adding two tranches on a 10% step with a 10% stop raises total risk from 1× to 2.75× your initial R. With equal-size tranches the same stack reaches 6× R. This is the central danger of pyramiding with a fixed stop.

The constant-risk stop is the stop level that holds your total open risk exactly at your original initialRisk (R) as the position grows. Formula: constantRiskStop = blendedAvgEntry − initialRisk / totalShares. As you add tranches, trail your stop up to this level after each add. For a 3-tranche decreasing stack (100/50/25) with initialRisk $1,000, you trail the stop to blendedAvgEntry − 1,000/175 = $100.00 — at which point the whole 175-share position risks exactly $1,000, the same as the first tranche alone.

A decreasing scheme (the upright pyramid) halves each add-on tranche: 100, 50, 25, 12 shares. The largest position is at the cheapest price, the blended average stays well below the current price, and the risk multiplier stays low (~2.75× for a 3-tranche stack). An equal scheme adds the same size at every price level: 100, 100, 100. This pushes the blended average up and, under a fixed stop, can multiply total risk to 6× or more. The equal scheme requires aggressive stop trailing; it’s common in systematic (Turtle-style) approaches where the stop is always raised with each add.

The Turtle system, documented by Curtis Faith in Way of the Turtle, adds one equal ‘unit’ every 0.5N (half an ATR, the average true range) the market moves in favour of the trade, up to a maximum of 4 units per market. After each add, all prior units have their stops raised to 2N below the most recent entry, so the entire stack’s stop is trailed up systematically. This equal-size approach is safe only because the stop always rises — fixed-stop equal pyramiding is far riskier.

If you have trailed your stop above your blended average entry — common after the position has moved strongly in your favour — totalRisk becomes negative. A negative totalRisk means the stop now guarantees a profit on the whole position rather than a loss. This is called a ‘free trade’ or ‘locked-in gain’. The calculator shows the sign correctly: a negative figure is a good outcome, not an error.

Averaging down means adding to a position as price moves AGAINST you, buying more at lower prices to reduce your average entry. Pyramiding does the opposite — it adds as price moves IN your favour, always at higher prices for a long. Averaging down concentrates risk in a losing trade; pyramiding compounds a winning one. They share the same blended-average formula, but the direction of price movement (and therefore the risk outcome) is opposite.

Most sources recommend capping total tranches at 3–4, regardless of scheme. The Turtle system used a maximum of 4 units. Beyond 4 tranches, the blended average converges toward the current price (for equal schemes) and even a small adverse move can wipe a large unrealised gain. The calculator limits addOns to 4 for this reason. If your stop is not trailed up with each add, fewer tranches (1–2) are safer for a fixed-stop approach.

Yes. The formulas — blended average, total capital, total risk and constant-risk stop — apply to any instrument where you can express position size in shares/units and price in currency per unit. For forex, treat lot sizes as ‘shares’ and the pip price as the entry/stop price; for futures, use the contract’s notional point value to convert price steps to currency risk. The calculator uses whole-number shares; for fractional-share brokers or mini-lot forex the same math applies with fractional units.

The risk multiple is totalRisk ÷ initialRisk, where initialRisk is the first tranche’s risk at the original stop. It tells you by what factor adding the extra tranches multiplied your original per-trade risk budget. A riskMultiple of 2.75 means your full pyramided position, under a fixed stop, would lose 2.75 times what the first tranche alone would have lost at the stop. Trailing the stop to the constant-risk stop brings the risk multiple back to 1.0.

No. Entry prices and stop prices are taken as exact fills. In practice, slippage widens the effective stop distance on each add-on and commissions raise the effective cost basis. As a conservative adjustment, add your expected slippage to each tranche’s entry price before entering it, and subtract it from the stop — this reduces the constant-risk stop and gives a slightly smaller position size. For high-frequency add-ons (e.g. 4 tranches) slippage can meaningfully change the blended average and risk figure.
