 So after months of work, I finally found out that these actions just make things complicated with no real positive impact. In fact, they just increase the learning time and an action like **Hold** will be barely used by a well-trained agent because it doesn't want to miss a single penny.

 ### Trading Positions
-If you're not familiar with trading positions, refer [here](https://en.wikipedia.org/wiki/Position_(finance)#Net_position). I'm not going to explain it but it's a very important concept and you should learn it as soon as possible.

 Again, in some trading algorithms, you may find numerous positions such as **Short**, **Long**, **Flat**, etc. As discussed earlier, I use only `Short=0` and `Long=1` positions.
