Demo honesty for yen specialists: mentee teaching notes
Posted: Sun Oct 04, 2026 10:36 pm
I've been mentoring a younger trader who wants to specialise in yen pairs, and the first month has mostly been about demo habits. These are my notes from our sessions, tidied up a bit.
Demo spreads on yen crosses can look better than live. I asked him to open a small live account alongside the demo and compare GBPJPY spreads at the same moments. During 07:00 to 08:00 London the difference was small. During the Tokyo lunch hour and near the rollover, the live spread was noticeably wider on several checks.
Size must be realistic. He started with a demo balance of 100,000 and 5-lot trades. On a real account of 5,000 he'd trade 0.2 lots. I made him reset the demo to the balance he'd really trade with.
Track slippage on demo anyway. Demo fills are usually instant at the price you click. Live fills aren't always. He now adds a pessimistic 0.3 pips to every demo entry and exit in his spreadsheet.
Practise the bad moments. BOJ days, Japanese intervention rumours, the 00:55 London fixing. I asked him to watch these on demo with a position open and note how fast price moved and how his stop behaved.
Log emotions even though it's fake money. "Bored", "frustrated", "felt like I had to trade". Those notes predicted his first live mistakes better than any statistic.
He's doing well. He's also discovered that demo results flatter everyone, which is the most useful lesson of the month.
