Elliott waves in trading: a correct direction can still produce a different result

Define the scenario observation

Write what the wave hypothesis expects and how that expectation will be reviewed. For example, a research observation might ask whether price later exceeds a recorded level. That statement contains no entry price, quantity, transaction cost or guaranteed ability to trade at the displayed turning point.

Use an explicit invented transaction

For arithmetic only, imagine buying 10 unleveraged units at 100 and selling all 10 at 102. The gross price-change result is (102 − 100) × 10 = 20 in the quote currency. If total transaction costs are 10, the net result is 10. These are assumed numbers, not a market recommendation.

Change execution while keeping the later chart

Now suppose the same hypothetical sale remains 102, but the entry is 102 and total costs remain 10. The gross result is zero and the net result is −10. The same later chart can accompany different transaction outcomes because the actual entry assumption changed.

Keep the evidence separate

A directional scenario score, a simulated transaction result and an actual account statement should not share one success label. Preserve the original scenario, explicit fill assumptions and costs. The exercise explains accounting boundaries; it does not validate a trading strategy or prescribe position size.

A teaching plan: hypothesis, condition and fill

This is a separate fictional purchase of an unleveraged asset, with quote currency equal to account currency. Record structural origin I=100, a first high 110 and an assumed retracement 102. The research condition is a completed bar closing above 103; separately assume a subsequent fill E=104. Risk stop S=101 is chosen above I=100 without changing the structural rule. Target 112 is only a conditional plan field; neither reaching it nor selling there is assured.

Before the next observation, retain source, interval, available bars, record time and scenario version. For balance 10000, set teaching budget R=100: arithmetically 1%, not a recommended percentage. Under the costs and allowance below, quantity 24 has planned loss 98. If the condition never occurs, no fill exists, or revised terms fail the budget check, record “no simulated trade.” Check the budget before admitting a new simulated trade; always record any actual fill, even if it breached the plan. Append changes as a new dated entry while preserving the original plan.

An entry condition is not an execution price

Check only a completed bar against the strict condition “close above 103.” An intrabar touch, the bar’s high, or a close exactly at 103 does not satisfy it. Record when the close became available; only afterwards consider the assumed fill E=104. Do not award an earlier intrabar price using knowledge of a later close.

E=104 is a separate assumption in the teaching arithmetic. An actual market order does not guarantee that price; a limit order might not fill. Observing a close is not itself an exchange order. Availability, sessions and execution depend on the agreement and venue. Without a fill, do not attribute later price movement to a position. With a different fill, recheck risk and cash limits. This example describes no automated Elliott order-entry feature.

Planned risk with costs and a gap stress case

In this linear model, V=1 account-currency unit per price point per asset unit. With E=104 and S=101, distance d=3. Assume round-trip commissions c=0.4 per unit, adverse-execution allowance s=0.6 per unit and fixed round-trip costs F=2. Planned loss is L(q)=q×(d×V+c+s)+F=4 q+2. R=100 on balance 10000 is an exercise input, not a recommended risk level or guaranteed loss ceiling.

At q=24, L(24)=98. If actual purchase 104 is followed by a gap exit 99, the price loss is 5 per unit. Keeping the same commissions gives actual loss 24×(5+0.4)+2=131.6. Prices 104/99 already incorporate execution; do not add the 0.6 allowance again. It was a planning assumption, not an incurred cost or protection against every gap. A changing point value, different currency or nonlinear contract would require a different calculation.

Position size: round down and check cash

The exercise has quantity step 1 and minimum 1. Per-unit planned risk is 3+0.4+0.6=4, with 2 of fixed costs for the whole trade. Thus q=floor((100−2)/4)=24, where floor rounds down to an integer. L(24)=98, whereas L(25)=102>100. If the budget cannot cover the minimum quantity and costs, the result is 0 rather than a compulsory trade.

Check cash availability and lot rules separately. Notional 24×104=2496 is well below balance 10000 for this unleveraged purchase; costs also require cash beyond the notional. Quantity 24, notional 2496, budget 100 and planned loss 98 are different amounts. Collateral or broker-permitted leverage does not replace a risk calculation. The formula assumes constant V=1 and invented costs; it does not establish a suitable real-world position size.

Risk and reward: gross and planned ratios

Retain the fictional entry E=104, risk stop S=101 and conditional target T=112. Gross price reward is 112−104=8; risk distance is 104−101=3. Define the ratio specifically as potential reward divided by risk: priceRR=8/3≈2.67, or risk:reward 1: 2.67. This arithmetic excludes costs, execution allowances and gaps, and does not promise that the target will be reached.

Apply the same predefined model: q=24, V=1, round-trip c=0.4 per unit, adverse-execution allowance s=0.6 per unit and fixed round-trip F=2. Planned risk is 98; planned net reward at the target is 24×(8−0.4−0.6)−2=166. Hence netRR=166/98≈1.69. These are two conditional outcomes including costs and an allowance, not a realized return or probability. Once actual fills are known, do not count the allowance again.
