IronPeak FX showed a completely different price spike than every other broker

I've traded major forex pairs for years and have accounts with multiple brokers.

Last week one of my positions on IronPeak FX was stopped out by an enormous price spike that appeared for only a few seconds.

Afterward I checked TradingView along with two other brokers and couldn't find the same move anywhere. The spike only appeared on IronPeak FX.

When I contacted support, they dismissed my concerns and claimed every liquidity provider is different.

That explanation doesn't really satisfy me because the difference was massive enough to trigger liquidations. I'm still waiting for someone to explain why their pricing looked completely different from the broader market.
