Don't ignore the spread on CFDs, especially in illiquid hours
Learned this the hard way trading indices pre-market a while back. Placed what I thought was a tight stop, market gapped against me a bit, but the real kicker was the spread widening significantly, triggering my stop much further out than anticipated. Cost me a decent chunk because I didn't account for the execution risk when liquidity dried up.
That's a tough lesson to learn, but a crucial one. It really highlights how market conditions, not just price action, can dictate execution quality, especially with instruments like CFDs during off-peak hours. Always good to factor that into risk assessments.
