i think that this strategy is good for those traders who has a lot of money in his account and can allow negative floats for long time....because sometimes market will move alot of pips and then come back to its original price in months...so if we are using this strategy, then we should invest so much money that it can cover the negative floats of our opened position for a long time.....but i will never follow this strategy, because if market moves significantly, then it will be hard to save my account from margin calls ...it also means that we are trading blindly and do not follow market news and analysis....so we should get every news and analysis about forex market and then trade according to that...........
