You see the spread. You think that's what the trade costs. It's not even close.In Episode 7, David Axtell breaks down the real cost of executing in FX markets — and explains why the visible bid-offer spread is just the tip of the iceberg. For institutional-size orders, implicit costs from market impact, timing risk, and opportunity cost typically run two to five times higher than the spread itself.David walks through how market impact follows square-root scaling laws — doubling your order size doesn't double your cost, it increases it by roughly 40%. He explains why splitting a large order into four pieces can cut aggregate impact by half, and why executing too aggressively can cost more than executing too slowly — but sometimes you have no choice.The episode covers transaction cost analysis (TCA) — the systematic framework institutions use to measure what they're actually paying. From implementation shortfall methodology developed by André Perold in 1988 to modern multi-benchmark approaches comparing arrival price, VWAP, and peer performance, David explains how leading desks identify where execution quality is leaking and how to fix it.He also addresses best execution obligations under MiFID II and Dodd-Frank — the regulatory frameworks requiring firms to document their execution processes, monitor quality systematically, and demonstrate they're achieving the best possible outcomes for clients.Whether you're a corporate treasurer wondering if your bank is giving you fair pricing, a trader optimising execution strategy, or a risk manager building a TCA framework — this episode gives you the tools to understand what you're really paying.Next Episode: When Spot Goes Wrong — settlement risk, Herstatt risk, CLS, and what happens when trades fail to settle.Based on: Chapter 5 of FX Cash Products by Luigi Rondanini and David Axtell, forthcoming from Rondanini Publishing.

Episode 6 explores the evolution of FX execution from voice-based relationship trading to sophisticated electronic and algorithmic methods. David Axtell draws on 35 years of experience to explain when each execution channel makes sense and how to choose strategically.The episode covers voice trading's continued relevance for large trades (£50M+), complex structures, and stressed markets where electronic quotes disappear. Single-dealer platforms offer relationship-based pricing with comprehensive product coverage but sacrifice competitive tension. Multi-dealer platforms provide price competition that typically saves 2-4 pips through simultaneous quote comparison from 8-15 banks.David explains ECNs (Electronic Communication Networks) like EBS and Reuters Matching, algorithmic execution strategies including TWAP and VWAP, and high-frequency trading firms that now account for 15-20% of major pair volume. Real examples include his strategic approach to converting Saudi riyal receivables—using electronic platforms for routine $5M trades but voice relationships for a one-off $50M transaction that required negotiation.The episode concludes with a framework for execution method selection based on trade size, currency pair liquidity, time flexibility, and market conditions. Transaction cost analysis (TCA) receives practical coverage showing how to measure execution quality and drive systematic improvement.By the end of this episode, you will be able to:1. Distinguish between voice, single-dealer, multi-dealer, ECN, and algorithmic execution methods2. Select appropriate execution channels based on trade size, currency pair, and market conditions3. Understand when relationship-based voice trading outperforms competitive electronic platforms4. Recognize how algorithms minimize market impact for large orders5.

Luigi Rondanini takes over the mic to reveal Season One's roadmap: 18 episodes covering spot, forwards, swaps, and NDFs. Behind-the-scenes challenges of producing across 8 time zones, plus a teaser about a Riyadh story David doesn't know yet.Next Episode PreviewEpisode 6: Transaction Costs - David Axtell returns to explain how to measure what you're really paying when executing FX trades. Explicit costs, hidden costs, total cost of execution. Critical practical knowledge for anyone trading FX.

Episode 5 begins Part II: Spot FX with comprehensive coverage of how spot transactions actually work from trade agreement to final settlement. David Axtell draws on decades running treasury operations to explain the mechanics that underpin seven and a half trillion dollars of daily FX trading.The episode explains why spot settlement takes two business days (T+2) rather than being immediate, covering historical context from the telex era through modern electronic systems. Value date calculations receive detailed treatment including business day rules, holiday adjustments in both currencies, and complications from Middle Eastern Friday-Saturday weekends versus Western Saturday-Sunday weekends.David walks through the complete settlement flow: confirmation generation, payment instruction transmission to operations teams, movement through domestic payment systems (Fedwire for dollars, TARGET2 for euros, BOJ-NET for yen), and the critical timing around cut-off deadlines. The 1974 Herstatt Bank failure provides historical context for settlement risk—banks had paid Deutsche marks to Herstatt but never received promised dollars when German regulators closed the bank mid-settlement cycle.CLS (Continuous Linked Settlement) solved this principal risk through payment-versus-payment mechanisms across eighteen major currencies, processing over six trillion dollars daily during a seven-to-noon Central European Time window when all relevant payment systems operate simultaneously. The episode concludes with market session analysis showing how liquidity varies across Asian (quiet), European (building), and London-New York overlap (peak) sessions, plus introduction to the learn.rondanini.com education platform.The Trading Floor with David Axtell

Foreign exchange is the largest financial market in the world—but who's actually in it?In Episode 3, David Axtell breaks down the five key player groups: banks and dealers who provide liquidity and take proprietary positions, corporates hedging commercial exposures, asset managers building currency allocations, central banks conducting monetary policy and market interventions, and hedge funds running speculative strategies.Each participant brings different objectives, time horizons, and information advantages. Understanding who's on the other side of your trade matters—because it shapes pricing, liquidity, and market behavior during both normal conditions and stress periods.David shares real examples: the Swiss National Bank's multi-year defense of the EUR/CHF floor (and its eventual abandonment in January 2015), corporate treasurers caught between FX volatility and board pressure, and George Soros' famous bet against the Bank of England in 1992.Whether you're executing hedges, managing portfolios, or trading directionally, knowing your counterparties' motivations gives you edge.This episode is part of The Trading Floor series—a practitioner's guide to FX markets based on 35 years of institutional experience across London, Riyadh, Doha, Dubai, and Singapore.Next Episode: Forward points and FX swaps—the mechanics that drive 60% of daily FX volume.Based on: FX Cash Products—the book soon available through Rondanini Publishing.
