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.

All-In Cost & Spike Logger (cTrader)

This cTrader indicator automates your spreadsheet tracking. It runs directly on your chart, calculates the real-time All-In Cost (live spread + your inputted commission converted dynamically to pips), and logs any flash-widenings to the cTrader Journal during your defined killzone.

Code: Select all

Operational Considerations for MetaTrader

Server Time Offsets: MetaTrader brokers (including IC Markets) universally set their server clock to GMT+2 (or GMT+3 during US DST) to maintain 5 daily candles per week. Adjust InpSessionStart and InpSessionEnd to match the broker's clock (e.g., if London open is 07:00 UTC and the server is GMT+3, set InpSessionStart to 10).

State Hysteresis: Both scripts implement a latch (g_isSpiking) so that a single 3-second flash widening is counted and logged as one spike event rather than flooding your log with 100 entries for every tick while quotes stay elevated.

Posted: **Wed Sep 23, 2026 8:05 pm**

Here is the reality of bringing this to TradingView: Pine Script has a fatal blind spot for true spread logging.

TradingView charts are constructed using a single price feed (typically the Bid price). Pine Script does not have native, tick-by-tick access to simultaneous Ask and Bid variables like cAlgo or MQL. When a prop firm's B-book feed artificially widens the spread by pushing the Ask price up during the London open, it usually happens without a trade printing. To TradingView, that event is completely invisible.

Because we cannot track true spread manipulation in Pine, I have adapted this script to track the next best thing: Killzone Microstructure Volatility & Commission True Cost.

It dynamically converts your USD commission into its exact pip equivalent for the chart's specific pair, highlights your London killzone, and tracks 1-minute liquidity sweeps (whip-saw wicks) that act as a proxy for thin, toxic order books.

Why your cTrader/MT5 scripts will always be superior for this:

Keep running the cTrader and MT4/MT5 versions on a cheap VPS. They calculate the spread array locally via direct TCP hookups to the execution server.

When a prop firm flashes a 4-pip spread on GBPJPY for 800 milliseconds right at 08:00:01 London time, the MT5 script logs it instantly. TradingView will never see it because a trade didn't execute at that Ask price to form a candle wick. Use this Pine script to visualize the Killzone and benchmark your baseline commission drag, but rely on your cTrader logs for the raw, unedited truth about platform manipulation.
