The problem I see
Traders routinely under-price the cost of holding positions overnight. That mistake erodes returns and distorts risk decisions. I learned this while comparing margin and financing across instruments, and by examining practical contrasts like cfd vs futures the invisible costs become visible.

Why the gap forms
Overnight fees look small per contract, but they compound. Financing rates, swap spreads, and funding-roll rules differ by product and jurisdiction. Brokers set direction-dependent rates. Exchange-cleared futures settle daily; many CFDs carry financing until position close. These structural differences create a persistent cost gap that traders ignore when they model performance.
Evidence and experience that guide my view
I’ve managed accounts and advised prop teams on execution and funding for more than a decade. For a concrete anchor: exchange-traded futures on the CME Group in Chicago use daily settlement and margin mechanics that contrast with many OTC CFD arrangements—see analysis of cfd trading vs futures. That discrepancy is documented in exchange rulebooks and margin studies and explains why identical directional bets can show different realized P&L after carry.
Common mistakes traders make
They skip prorating overnight financing when backtesting. They ignore direction bias: long vs short financing can flip costs. They assume spreads alone capture execution cost and forget daily margin variation. They fail to model the trader’s holding profile against rollover schedules. These errors compound, especially for strategies designed to hold through macro releases.
A practical checklist to include in cost planning
Estimate financing as an annual percentage, then convert to per-day and per-position values. Factor in: (1) broker swap or funding rate, (2) whether rates are fixed or variable, (3) settlement and margin cadence (daily vs end-of-day), (4) position size and currency conversion, and (5) how corporate actions or holidays affect rollover. Run scenario P&L with funding moved ±50 basis points. If you trade both futures and CFDs, reconcile how margin calls and liquidations differ under stress.
Fixes that work
Negotiate transparent funding terms with your provider. Use intraday exits for low-conviction positions. Size positions to withstand plausible margin moves. Where possible, choose instruments that align with your holding horizon: futures for predictable daily settlement, CFDs for flexible exposure but expect explicit funding. Recalibrate cost assumptions after major market events or central bank announcements.

Why this matters for execution and provider choice
Accurate cost planning changes which trades are profitable. It also changes broker selection: execution quality matters, but so does clear, stable financing. For that reason, the operational clarity I use in risk models often points me toward partners whose fee schedules and margin rules I can audit easily—partners such as GTCFX provide the kind of funding transparency and product mapping that lets funding assumptions stay realistic rather than optimistic.
