My suggestion (after some months of experience with this stock on t212):
Market order makes your order go through faster, but be prepared for some hefty slippage. This stock is traded via venue at special specified times throughout the day.
Limit orders take longer but are much safer.
Dont trade this stock. Daily volume too small, spread large. If you like trading this, I would recommend cryptoexchange and trading btc directly. Argo heavily tied to btc because they mainly mine that.
If you like Argo, I would buy and hold.
Cheers and good luck!
