Tradingview provides unique opportunity to watch round numbers both EURUSD and USDEUR.
Round numbers do work as support and resistance. Perhaps the only levels that one can rely on.
But it should be remembered that American continent watches and trades primarily USD vs EUR, while in Europe it is the opposite case.
Watch for round numbers confluence on mirror (inverted) charts, i.e. USDEUR and EURUSD to find true sopport and resistance.
The top of eurusd was round number confluence 0.81 - 1.23 level.
Right now, the major resistance is 85 level (usdeur). If price will get through that it will stumble at 1.17 (eurusd)
