About the trading costs of CFD providers, specifically LMAX, - outside of overnight financing - are average but about on par with alternate offerings.
However, I think that for liquidity absorption, LMAX has an advantage over all other solutions I was able to check (many), because for a similar global execution costs (spread + commissions), the LMAX costs almost exclusively rely on the commissions, not the spread. It makes for a very special situation where the spread is the tightest possible. I am assuming that this is a positive fact for a replication engine which will meet potentially meet more and closer price levels to feed. Although the LMAX top of the book is not the thickest I’ve seen, the LPs will fill the voids immediatly after the retail traders take it, so I believe that the particular combination of close Bid-Ask (related to the crypto world, not generally) + high commissions is kind of intriguing but an appropriate cocktail for Darwinex.
Otherwise, indeed the swaps of ALL trading brokers (outside some exchanges) are …high. Annually, it’s quite much. Having this in mind, as funny as it is, it becomes inappropriate to buy and hold unless you have strong beliefs that the market will really perform much directionnally. Hence, short term / active trading will be favoured, or mid-term trading as long as watched for. It’s not really the kind of market that you want to forget and kiss goodbye facing far stoplosses since the amplitudes are too strong too often. Also the perpetual trading hours (except sundays for LMAX) makes it kind of hard and tiring because you could go to sleep and wake up with a surprise (the asian session is not the most tame to deal with)
