I think forex can be a good choice but I can not say the best option for retirement or parents. Forex is very risky and because of money there is also the possibility of losing money. A pensioner who last made money is important for his survival. So one with better knowledge should go for forex trading. and I found that with my experience and knowledge, forex trading is the best for all types of society, namely as retired people and job holders because both people can get clothing and have the same opportunity for investment. But it is very helpful for people who have retired!
