You will buy 2 options to enter the Long Straddle, and 2 trades to exit the Long Straddle (or exercise at least one of them). Hence, those brokerage and commissions should also be deducted to get an exact amount of profit value.

What is the maximum loss for Long Straddle Option Trading?

What are the risks in trading Long Straddle Option ?
Long Straddle is considered to be one of the safest bets in the options trading - however, you must note that you are buying 2 options, so you are at the risk of loosing the entire money you will spend in the hope of getting unlimited profit potential on upside and limited profit potential on the downside.

- Time decay will hurt this Long Straddle position. Hence it is advisable to enter this position with atleast 3 months of expiry and exit when less than a month is remaining since time decay rate is highest in the last month. (See Options Time Decay: Explained with Examples).

- The option trader ends up paying a big price while entering Long Straddle since he/she has to buy 2 ATM call & put options. Since they are ATM options, they have the maximum time decay value which increases the cost of buying Option Straddle. The same factor hurts negatively at the exit since there is less time left to expiry and time value already erodes a lot of profit potential.

- Bid and Ask spread may not always be favorable to the Long Straddle option trader. There may be big wide gaps in the prices of ATM calls and puts both at the time of entry and exit from Long Straddle
