Prop firm spreads versus IC Markets raw is the comparison that keeps me honest about funded accounts.
Marketing pages blur. My sheet does not. I pick the same London hours, the same pairs I actually trade, and I write down what the platform showed — not what a review site scraped last year.
Columns that matter to me
- Median spread in the London killzone
- How often the quote flashes wide then snaps (usable vs trap)
- Whether commissions are buried so "spread" looks prettier than all-in cost
If the prop path is consistently wider, my lot ladder and playbook shrink. I do not try to force personal-account R-multiples onto a slower tape and then blame psychology.
For those running both: which pairs still look workable on the firm feed, and which did you exile back to personal capital only?
Commission schedules matter in the comparison too. A tighter raw spread with a fee can still beat a commission-free prop quote that prints wider every London open. All-in cost per round turn on a typical scalp size is the only number I argue from.
Hi LondonScalper,
Prop firms are in the risk management and fee-generation business; they route via B-book liquidity providers that inherently pad spreads during volatile transitions. IC Markets Raw provides true ECN aggregation, meaning its order book absorbs London open liquidity sweeps rather than artificially fading them with widened quotes.
When scalping 1-minute and 5-minute price action for 10-15 pip targets, an extra 0.4 pips in hidden costs degrades your R-multiple over a 100-trade sample size. A 0.0 pip raw spread with a $7/lot round-turn commission is a ~0.7 pip true cost on EURUSD. A prop firm advertising a "tight" 0.5 pip spread but burying a $6 commission is running a 1.1 pip true cost.
The Pair Exile List (Prop vs. Personal)
Workable on Prop Feeds: EURUSD, GBPUSD, and USDJPY. Baseline interbank liquidity on these majors is deep enough that even with a prop firm's artificial markup, the all-in cost rarely exceeds 1.2 pips during the London killzone. XAUUSD (Gold) also remains viable if you scale lot sizes to its ATR, as the point-value to spread ratio absorbs the B-book padding.
Exiled to IC Markets (Personal Capital Only): GBPJPY, GBPNZD, EURAUD, and XAGUSD (Silver). During the London open, prop feeds frequently flash-widen crosses by 3 to 5 pips. These synthetic spikes hunt structural stops that IC Markets' raw feed would never touch. Silver is notoriously toxic on prop accounts; the baseline spread is padded so heavily that scalping lower-timeframe structure becomes a negative expectancy game.
Preserve your own money. Scale with the market's money. Exponential growth is the ultimate key.
