Assumptions & caveats
One round turn per trade. Each CSV row is a position close (entry + exit, 1 contract), so the round-turn commission — 2 × per-side — is charged once per trade. A single rate is applied to every symbol; the sample mixes MES/MNQ/MCL micros (~$0.62/side), so it is an approximation.
Subscriptions are prorated by the sample's calendar-day span over 30.44 days/mo. Load a full month and you are charged a full month; load 9 days and you are charged ~9/30 of it.
Net PnL (card) = gross − commissions − prorated subscriptions. Profit Factor (card) is recomputed net of commissions per trade. Win rate, drawdown, and the equity curve stay gross.
Data feed list is AMP's published CQG schedule. Default is CME Equity Indices — Top-of-Book ($5); the Market-Depth (L2) version of that line is $17. EUREX is listed in EUR.
Tax = blended 1256 rate: 60% × 15% long-term + 40% × 24% ordinary (assumed bracket, fixed) + your state's top rate on the full gain. It applies only when net profit is positive; no state mirrors the 60/40 split, and short-term 1256 gains never qualify for state long-term exclusions.
Break-even / trade = total period costs ÷ trade count: the average gross each trade needed to clear costs.
