-### Hyperopt with MongoDB
-Hyperopt with MongoDB, is like Hyperopt under steroids. As you saw by
-executing the previous command is the execution takes a long time. 
-To accelerate it you can use hyperopt with MongoDB.
-
-To run hyperopt with MongoDb you will need 3 terminals.
-
-**Terminal 1: Start MongoDB**
-```bash
-cd <freqtrade> 
-source .env/bin/activate
-python3 scripts/start-mongodb.py
-```
-
-**Terminal 2: Start Hyperopt worker**
-```bash
-cd <freqtrade> 
-source .env/bin/activate
-python3 scripts/start-hyperopt-worker.py
-```
-
-**Terminal 3: Start Hyperopt with MongoDB**
-```bash
-cd <freqtrade> 
-source .env/bin/activate
-python3 ./freqtrade/main.py -c config.json hyperopt --use-mongodb
-```
-
-**Re-run an Hyperopt**
-To re-run Hyperopt you have to delete the existing MongoDB table.
-```bash
-cd <freqtrade> 
-rm -rf .hyperopt/mongodb/
-```

 ## Understand the hyperopts result 
 Once Hyperopt is completed you can use the result to adding new buy 
 signal. Given following result from hyperopt:
