Market Manipulation

I have a 10k funded challenge from The Forex Funder, and use ThinkMarkets as the broker as this was the only option available. Today I opened a trade on US30 and saw my potion was in a negative. But on my other broker it was in profit. I then checked the price movement of 4 other brokers and ThinkMarkets was completely opposite to the actual market price. There is clear market manipulation going on with this prop firm or broker. They manipulate the markets so you lose your prop firm challenge. It’s a whole mess, market manipulation is illegal according the FSC’s website. I hope they take action. I have attached screenshots of 5 different brokers at the same time and you can see the discrepancy in the 1H candle.
