Creating an ideal price feed Solution

As you know the forex market is non centralized; hence, brokers can cheat clients in many ways i.e. widen spread, requoting, stoploss hunting and etc. However, there is one of the legal ways that they can cheat is price feed variation. As expert advisors are dependent on proper price feed to execute the algorithm, broker can pause or skip the price feed at critical time to disrupt the algorithm trading. For instant if the algorithm run on the 5 minute charts, but what happens when there is no price feed at exactly 05:00:00? I am looking for a solution to combat this issue. What if we combine multiple price feed from different brokers to create a deal price feed to minimize the number of tick/price gap?
