Strategy tester using BTC as the deposit currency. What does this mean?

 

Hi everyone,


I have an odd question about something I have noticed in the strategy tester. I am using a bitcoin as my deposit currency (since I am trading BTCUSD and want to ensure my fees are calculated in btc). 


Next to the deposit section, there is a dropdown box with a value selection between 0 and 8 (shows 8 in the screenshot above). 

Can anyone possibly tell me what do these values actually mean? I am struggling to find any answers in the documentation and it's important to know since changing this value significantly impacts my strategy tester results. 


Any help would be much appreciated!

 
Digits

I think decimal digits.
