Step 1: Have you search for this issue before posting it?

Yes

Step 2: Describe your environment

• docker octobot 1.0.8
• DipAnalyserTradingMode

Step 3: Describe the problem:

Whenever a sell order is fullfilled, I see notifications containing 'on Bitvavo Trade profitability : +0.0000% ' while related buy order is definitly was fullfilled at lower price (at least 3%). Although its just a display thing, I would love to know the real % by notification instead of rather disappointing 0%
If it's related to specific exchange for some reason, that would be fine too to just close this issue.
Expected behavior
A proper value of achieved profit in the notification so I can see it kinda adheres to the trade mode parameters.

Steps to reproduce:

1. have strategy trigger buy order
2. see sell orders creation at proper prices (seems good so far)
3. wait for sell fullfillment

Observed Results:

• Trade mechanism seems good
• just calculation of profit % (only viewbale in notification?) is alway 0.0000%
