A gold trading system: the first London hour is the stop

Four lines for XAUUSD. Not a forex rule with a new ticker.

Direct answer

A gold sitting that names London’s first hour also names permission, trigger, invalidation, and size. This page copies one finished record: XAUUSD, H1, file clock GMT, week 2016-10-24 → 2016-10-28.

Permission: XAUUSD, H1, the first London hour of each London day in that week.

Trigger: that bar’s high and low are the range. Monday 2016-10-24 07:00 GMT (BST, so London 08:00 local maps to file 07:00): high 1266.3, low 1265.0.

Invalidation: the first later bar through that high or low ends the sitting. 08:00 GMT printed 1264.6.

Size: write where you are wrong first. Size stayed 0.1. No ticket.

The record is The first London hour is the stop. The method note is Write where you are wrong first. This page does not paste the EURUSD first-hour sitting onto gold.

How to judge

Three checks before the product pitch.

Does it serve gold and London? “Same as EURUSD” is not a system. This sitting is XAUUSD. EURUSD has a different public sitting.

Do the four lines carry this sitting’s numbers? If 1266.3, 1265.0, and 1264.6 are missing, it is not this page.

Is there a record? A “London gold system” with no date and no OHLC lives in speech. Session complete: Trades 0, +0.00.

What we do

Desktop opened an H1 CSV aggregated from Dukascopy-style XAUUSD ticks. File clock GMT. The week was the last complete Monday–Friday in that file. The sitting ended at 08:00 Monday. The cover of the case is the stop bar. This page uses the end screen of the same sitting: Trades 0.

Pip names stay on the XAUUSD pip calculator: 0.01, 0.10, 1.00. Those three rows did not change.

Who should skip

Skip it if you wanted a live London buy zone. This is a finished practice sitting.

Skip it if you wanted the EURUSD first-hour range copied over. Different market, different tape.

Skip it if you wanted a win-rate table. One stopped sitting does not print that number.

Skip it if you wanted a .bqproj. This page does not attach one.

Frequently asked questions

Is 1265.0 a live stop in dollars?

No. It is the low of Monday’s first London hour on this file. There was no broker ticket.

Why not say the same rule fits EURUSD?

The EURUSD sitting used that sample’s first hour. This sitting used London’s first hour on XAUUSD, with the GMT/BST map written down. The records stay apart.

Can I walk the file myself?
