I have read many thread... but at the end i have not understand what is the best bot Please let me know your experience
Thanks

A best bot would may not be comprised of a single software product, in some cases it can be a suite of bots or it can depend on your account size and acceptable trading style.

You should look at consistent returns over a long period of time, bots that are founded by real world trading, and most importantly it should have unscrupulous money management capabilities that can be scaled to your account size while strictly adhering to your acceptable risk settings.

Check out the stats on an EA I'm testing, I took one huge hit early on but it rebounded nicely and has an ROI of 59% for the past month.

PM me if you want more info

There really is no 'best' Forex robot. There are a lot of good ones which can make you a lot of money but remember each comes with their own risk of loss as well. You have to remember each EA has a different level of risk so make sure you choose one you're comfortable with
