Frequently asked questions
How is the average calculated?
Total amount spent divided by total size, which is the size-weighted average fill price.
Are fees included?
No. Raise each price slightly to include fees, or use the trading fee calculator.
Does averaging down guarantee a recovery?
No. It lowers your average, but if the price keeps falling your loss grows too. Decide in advance how many times you will add.
