For stop loss hunting you can read liquidity searching, there is no doubt that stop losses are used by big traders in that you can usually tell where there will be a heavy load of stops, if these can be broken thru it can cause a significant move, they are also very useful for filling large orders that need to be executed. Do brokers hunt our stops? I won't say it doesn't happen but usually it's because our stops are in obvious places that they get removed, not because we are be targeted.
