Above definition says: I have five parameters I want to randomly combine to find the best combination. The above definition says: I have five parameters I want to randomly combine to find the best combination.
Two of them are integer values (`buy_adx` and `buy_rsi`) and I want you test in the range of values 20 to 40. `buy_rsi` is an integer parameter, which will be tested between 20 and 40. This space has a size of 20.
`buy_adx` is a decimal parameter, which will be evaluated between 20 and 40 with 1 decimal place (so values are 20.1, 20.2, ...). This space has a size of 200.
Then we have three category variables. First two are either `True` or `False`. Then we have three category variables. First two are either `True` or `False`.
We use these to either enable or disable the ADX and RSI guards. We use these to either enable or disable the ADX and RSI guards.
The last one we call `trigger` and use it to decide which buy trigger we want to use. The last one we call `trigger` and use it to decide which buy trigger we want to use.
