# EV:GO (not in use anymore)

In order to mitigate toxic order flow generated by unavoidable lags in price propagation we’ve built a novel, ultra fast on-chain oracle to complete the used external price oracles in the early days of Nabla. It was able to signal potentially dangerous price movements before the actual price reaches the chain. Due to our novel inhouse HFT pricing engine, we don't need the additional EV:GO protection anymore.
