4h USDZARSupport at 18.21, which coincides with 50-day MA and 61.8% Fibo is holding support. A failed break below 18.21 will allow the pair to retest the resistance range between 18.48 and 18.55. A break below 18.21 will however see the pair slide back between the support range between 18.00 and 18.10.
