Stop loss hunting is real, but it`s not done by your broker. (as long as you use a fully regulated one)
It`s done by big firms and banks, etc.. that are trading the amount of money I can`t even imagine. For example, if a rally is kinda obvious and everyone is getting in buying, they can`t really do the same thing bcoz they`d get a huge slippage and not a lot of profit, instead what they do is, they have the ability (and amount of money) to drive the price lower into obvious support levels and previous lows where most ppl are placing they stop losses (aka sell orders), so they can absorb all that and fill their buy orders with a better price. Or something like that.
For me a scenario like this is much more believable then brokers actually monitoring my SL levels and trying to stop me out from my smallass 2 minilots trade. Regulated brokers cannot do such things anyway bcoz they are closely monitored and it would count as fraudulent activity.
