The maximum possible loss of the trade according to the strategy, as well as the maximum percentage loss.
Let's look at how the value for the Drawdown column is calculated:
In this example, we bought 1 share of AAPL at the opening on June 15 and sold it at the opening of June 22. The initial capital was $1000.
The minimum value to which the share price has decreased since the purchase is $332.58 on June 15, therefore the maximum possible loss in this transaction is $333.25 - $332.58=$0.67, for a percentage of (0.67/(333.25*1))*100% = 0.20%.
