Lesson 01

Reading an economic calendar

A calendar gives you four things per release: the time, the impact rating, the forecast and the previous figure. The number that moves markets is the surprise — actual against forecast — not the actual figure itself. A terrible number that everyone expected moves very little.

Learn the handful that matter for your instrument. For gold and the dollar that is US CPI, non-farm payrolls, FOMC rate decisions and the press conference that follows them, and to a lesser degree PCE and retail sales. Everything else is noise you can trade through.

Check the calendar before the session, not after a spike. Two minutes at the start of the day tells you which hours are dangerous.

Take away

Markets price the forecast in advance. Only the surprise moves price.

Lesson 02

Why spreads widen before a release

The spread is the price liquidity providers charge for standing in the middle. Immediately before a scheduled release, standing in the middle is enormously risky, so they either widen dramatically or step away entirely. A gold spread of 15 cents can become two dollars for ten seconds.

This matters even if you never trade the news, because a widened spread reaches your stop loss. The bid can fall to your stop while the mid-price has barely moved. You were not stopped by the market; you were stopped by the spread — and that is a legitimate fill, not misconduct.

The defence is distance. A stop placed inside the instrument’s normal news-time spread will be hit at some point with certainty.

Take away

A stop closer than the widened spread will eventually be taken by the spread alone.

Lesson 03

Slippage and gaps explained

Slippage is being filled at a different price than requested because the market moved between your click and the server. Gapping is price jumping with no trades in between, so there is no price at your level to fill at.

A stop loss is a market order that triggers at a level. If price gaps through the level, you are filled at the first available price beyond it, which can be materially worse. This is why a stop caps your intended risk, not your maximum possible loss, and why guaranteed-stop products cost extra.

Weekend gaps are the common case: Friday close to Sunday open on gold and crypto can be a substantial distance, and nothing you had on the chart operates across it.

Take away

A stop is a trigger, not a guarantee. Gaps fill beyond it, and weekends are where that happens.

Lesson 04

Stop hunting versus normal spike behaviour

The suspicion is common: price dips exactly to your stop, then reverses. Before concluding anything, check the timestamped tick data. Compare your fill against the actual bid at that millisecond, and compare your broker’s low against another feed for the same second.

Almost always the explanation is ordinary. Stops cluster at obvious levels — round numbers, the previous day’s low, the visible swing. Everybody puts them in the same place, so a move into that pocket triggers a cascade of market sell orders that carries price further, and it snaps back once they are exhausted. No conspiracy required; the clustering does it.

What you can act on: place stops away from the obvious pocket, size so that a normal spike does not reach you, and keep a record. If your fills genuinely diverge from an independent feed on a repeatable basis, that is evidence worth taking elsewhere. A feeling is not.

Take away

Stops cluster where everyone puts them. Move yours off the obvious level and check tick data before blaming the broker.

Lesson 05

Three ways to trade a release safely

Stand aside. Flatten before the release and re-enter afterwards. The most reliable option, and the one professionals use most often. You give up nothing except the trades that were going to be lotteries.

Reduce and widen. Cut size to a quarter and widen the stop so that the widened spread cannot reach it. Same money at risk, far more room. You accept a worse entry price for the privilege of surviving the noise.

Trade the aftermath. Wait for the first five to fifteen minutes to pass, let the spread normalise and the initial spike resolve, then trade the direction that survives. You miss the first move and avoid every reversal in it.

What does not work: leaving a normal-sized position with a normal stop through a high-impact release, and hoping.

Take away

Flat, or smaller with a wider stop, or after the dust settles. Never unchanged and hopeful.
