The broker is a very essential subject for trading. If the broker's spread is good, many benefits can be gained. Market maker broker spreads are usually not good. Details about the broker should be known before investing in trading.
Well.. Spread eats profits, and destroys many otherwise good strategies. Move higher. Some Market Makers offer many other good features, like guaranteed stop loss, and zero negative balance. I wouldn't blindly stare at nominal spread, since there is also a phenomen called slippage, which is essentially a hidden part of the spread.
1.7 is something I would still consider high. Fxview gives me 0.0 pips as spreads (on some currency pairs) and with XTB’s standard account the spreads start from 0.9 pips. So you could still explore some more options.
There are plenty of brokers nowadays actually and all of them offer exclusive conditions. It's difficult to help you to determine which broker will suit you most, beause every trader has his/her own needs in brokers. In your case you should pay attention to those brokers, which have tight spreads. However, if they have tight spreads, perhaps they will have commissions on withdrawals and transfers, because brokers also want to earn money. They offer you platforms for earning money, and you pay them back by commissions or spreads. So, here everything is difficult, but there are brokers with tight spreads I'm sure.
