Am totally new, so forgive my ignorance.Where could I get some info on what " no dealing desk forex trading" means.
Forex brokers who use this system work directly with market liquidity providers. When trading through a no dealing desk, instead of dealing with one liquidity provider, an investor is dealing with numerous providers in order to get the most competitive bid and ask prices. An investor using this method has access to instantly executable rates.

*The above is correct, but we are not ‘Investors’ as we do not actually buy or sell the asset, rather we are speculating on the derivitive.
Thanks.So, would it be more advisable to go through a broker with no dealing desk
In all honesty it will make no difference when starting out, both options would be fine as long as you chose a reputable broker.
True no dealing desk accounts are really only beneficial when trading very high volumes, more so than the average retail trader.
almost all brokers tell that they have “no dealing desk” now, but in real you can’t check it, because you never find the information how they work 
For making <10 000 $ it is not important!
If the broker is fully regulated or works with a large finacial institution then it can be trusted
Wanna believe!
