A good money management will keep your capital secure and will teach you how to reduce losses and increase you profits. A tight SL is considered to be most profitable. MM teaches you to use small lot sizes in your trades, use SL to prevent huge losses and use TP so that you ddo not miss profit. Also set a risk reqard ratio like 1:2, 1:3 or 1:4. It means that in 1:2 if your SL is 10 pips then your tp should be 20 pips.
