Muy buenas. Estaba leyendo este hilo https://www.bogleheads.org/forum/viewtopic.php?t=97899 en bogleheads.org y me he encontrado con este párrafo:
Also don't forget that you should pay for real time market data, because you should trade ETFs using limit orders. But for limit orders you should know the real time prices. And the market makers of certain EU domiciled ETFs increase the spread dramatically at random times and without notice. This is why you should carefully monitor the spread in real time, and buy only when the spread is tight. If you invest new money each month, then you must pay for the real time market data each month. If you invest quarterly, you only pay 4 months. I suggest not to buy ETFs without real time market data; what you win by not paying for real time data, you might lose it at unexpectedly high spreads.
¿Es cierto esto que comenta del spread? Yo siempre hago las compras mensuales del IWDA:AMS el mismo día y "a mercado". ¿Creeís que es una mala estrategia?
Saludos.
