Round numbers on EURUSD: do they attract price in the London morning?

[FXS London Scalper]

A common belief is that price is drawn towards the nearest 00 level during the London morning. It's possible to test.

Method:

• For each morning, note the distance from price at 08:00 to the nearest 00 level, for example 1.0800 or 1.0900.
• Record whether price touched that level by 12:00.
• Compare with a control: touch frequency of a random level at the same distance, for example 1.0837.

The control is the important part. If price touches 00 levels as often as random levels at the same distance, there's no magnet, just volatility.

What might be real: round numbers often have option strikes and clusters of orders. That could make price pause or react there, more than attract it.

A practical use, even without a magnet: avoid placing stops just beyond round numbers, where many others place theirs.

Option expiry data, published by some banks and news services, can show which round numbers have large strikes on a given day.

Has anyone done the comparison with a control level?
