Exotic pairs have trading hours too, and nobody mentions it
Posted: Thu Oct 29, 2026 4:38 am
USDZAR, USDMXN, USDTRY, and USDPLN do not trade with the same depth around the clock. Their liquidity depends heavily on when the local market is open, and outside those hours spreads can be several times wider.
For instance, the South African rand is most liquid during European and early US hours. The Mexican peso gets its depth during the US session. The Turkish lira has a reputation for sudden jumps when local markets are closed and headlines hit.
A scalper who treats an exotic like a major might open a trade at a quiet hour and find that spreads are far wider than expected, or that stops execute at prices well beyond the level set.
A practical approach is to build a simple table of average spread by hour for each exotic on the watchlist, then restrict trading to the hours when spreads sit within a defined limit. The data is easy to collect from a platform's own tick history.
Tick history on the platform makes the hourly spread table easy to build. Export a month of data, group by hour, and take the median and the ninetieth percentile. The upper figure matters most, since it shows how bad the bad moments get.
