After many back test with any brokers, the good results become when the spread is 0.1 0.5 max. in EURUUSD.
This results in triple-time account of 6 months with a moderate risk factor. If using money management according to the progressive gains the result can still be double the benefit.
I encourage the developer of this excellent bot offer this option button to increase lot as you rise in revenue account under moderate risk.
The bot has not yet offered good results from 1999 to 2005 even with the best spread. This simple fact makes us know that in any case have to be careful, especially now that the market is too volatile.
I do not recommend using the bot to spread over 0.6. I have not done changing the default back test settings, and are very good!
From my point of view the designer of this bot punctuation deserve the best, thanks for sharing
