Do you use Trailing stops in Optimizer ?

 

Do you use Trailing stops in Optimizer  or is there a difference with ticks compared to live ticks?

 
I do. You know your test is good when it replicates the real scenario.
 
Use the visual backtest to check how your trail stops works. Also careful with ticks, they are different between brokers and may give you a wrong impression that your EA works where it doesnt in a live environment.
