Trading without stop-losses will never be a good idea, if you want to be a successful trader, you should always learn to keep your account from great losses.
Using the stop loss is very important because it's help all traders to limit their losses and protect their account to avoid lossing the capital and i advice them to use also the money managment and risk managment because they have lot of benefits and advantages.
But what is most importantly is the size or the volume that you have to enter? I mostly close my trades manually. When I am confused about the market, I enter with low lot then if it gains profits, I will re-enter at appropriate price with normal lot and if it goes against me, I close it out. This way I won't be getting high loss. This works great for me and also increases the profit potential with low risk.
