How can i find all the ETF's traded on the liffe that have options? A friend told me that I'm better off with a synthetic call made with an etf + put like 5% out of the money with 1 month expiration and renew each month, than if I buy just the call 3 or 4 month out, because volatility, time, etc will make this call more expensive (even if one consider commisions in the previous case). Is he right.... is it true that a call 10% below current price is usually more illiquid than a put 10% below current price Tnx in advance
