The most liquid options are on the RTS index, Gazprom and Sberbank shares. Higher liquidity means less spread, which means higher profit (meaning the possibility of a quick sale in case of getting rid of options).
Depending on the chosen strategy, weekly, fortnightly, monthly and three-month options may have attractiveness.
When choosing between CALL or PUT, if the strategy is based on their direct purchase, it is necessary to take into account the current trend and the prospects for its preservation.
