Definitions of leverage and of leverage factor
Levarge in simple terms is how of your own money to how much of borrowed money.   So in 2008 Typical leverage ratios were Investment Banks 30:1 means that for every 1 Unit of Banks money [shareholders capital/ long term debts] there was 30 Units of borrowed money [from deposits/for other institutions/etc]. This is a very unstable situation as typically say you lent out 31 to someone else, half way through repayments, the depositors and other lends are asking you 30 back. You are sunk. Now lets say if you lent 31 to some one, but 30 was your moeny and 1 was from deposits/etc. Then you can anytime more easily pay back the 1 to the depositor. In day trading, usually one squares away the position the same day or within a short period. Hence say you want to buy something worth 1000 in the morning and are selling it say the same day. You are expecting the price to by 1005 and a gain 5. Now when you buy via your broker/trader, you may not be required to pay 1000. Normally one just needs to pay a margin money, typically 10% [varies from market to market, country to country]. So in the first case if you put 1000 and get by 5, you made a profit of 0.5%. However if you were to pay only 10 as margin money [rest 990 is assumed loan from your broker]. You sell at 1005, the broker deducts his 990, and you get 15. So technically on 10 you have made 5 more, ie 50% returns. So this is leveraging of 10:1. If say your broker allowed only 5% margin money, then you just need to pay 5 for the 1000 trade, get back 5. You have made a 100% profit, but the leveraging is 20:1.  Now lets say at this high leveraging when you are selling you get only 990. So you still owe the broker 5, if you can't pay-up and if lot of other such people can't pay-up, then the broker will also go bankrupt and there is a huge risk.  Hence although leveraging helps in quite a few cases, there is always an associated risk when things go wrong badly.
