When scalping, traders tend to employ a leverage that starts at 50:1 and may go as high as 500:1. Knowing the effect of leveraging and the optimal leverage Forex trading ratio is vital for a successful trading strategy, as you never want to overtrade, but you always want to be able to squeeze the maximum out of potentially profitable trades. Usually a trader is advised to experiment with leverage within their strategy for a while, in order to find the most suitable one.
When you trade forex, you're effectively borrowing the first currency in the pair to buy or sell the second currency. With a US$5-trillion-a-day market, the liquidity is so deep that liquidity providers—the big banks, basically—allow you to trade with leverage. To trade with leverage, you simply set aside the required margin for your trade size. If you're trading 200:1 leverage, for example, you can trade $2,000 in the market while only setting aside $10 in margin in your trading account. For 50:1 leverage, the same trade size would still only require about £40 in margin. This gives you much more exposure, while keeping your capital investment down.
Between 2003 and the end of 2004, the AUD/USD currency pair offered a positive yield spread of 2.5%. Although this may seem very small, the return would become 25% with the use of 10:1 leverage. During that same time, the Australian dollar also rallied from 56 cents to close at 80 cents against the U.S. dollar, which represented a 42% appreciation in the currency pair. This means that if you were in this trade – and many hedge funds at the time were – you would have not only earned the positive yield, but you would have also seen tremendous capital gains in your underlying investment. 
With Equivolume, you can plot price and volume activity on a single graph, instead of having volume added as an indicator on the side. This tool draws the bars following their traded volume at a precise point in time (the wider the bar, the bigger the volume). That creates a clear visualization of the volume increase or decrease of an asset’s diagram. A very handy feature for those strategies whose key factor is volume. How to change your table into Equivolume
