The Sydney open: any edge, or just something to watch?

[FXS London Scalper]

The Sunday evening Sydney open attracts curiosity. Before treating it as a trading opportunity, consider what typically happens:

• Very wide spreads in the first 15 to 30 minutes, often several pips on majors.
• Gaps from Friday's close, sometimes from weekend news.
• Thin liquidity: small orders can move price.
• Platforms and brokers sometimes reopen with a delay.

So any edge would have to be large to cover those costs. For most scalpers, the open is better as information than as a trading time.

Useful information it gives: whether there's a weekend gap, how big, and whether any news drove it. That helps plan Monday morning in London.

If you want to check whether trading it makes sense, a micro-lot test with spreads logged on several Sunday opens will show the cost directly. A worked example: a 3 pip spread on a 10 pip target is 30% of the target before slippage.

Has anyone made the Sunday open work consistently?
