Hi guys,
Am doing some reading in babypips on position size. I don't quite understand the following bold and underlined area:
Ever since he blew out his first account, he has now sworn that he doesn’t want to risk more than 1% of his account per trade. Let’s figure how big his position size needs to be to stay within his risk comfort zone.
Using his account balance and the percentage amount he wants to risk, we can calculate the dollar amount risked.
USD 5,000 x 1% (or 0.01) = USD 50
Next we divide the amount risked by the stop to find the value per pip.
(USD 50)/(200 pips) = USD 0.25/pip
Lastly, we multiply the value per pip by a known unit/pip value ratio of EUR/USD. In this case, with 10k units (or one mini lot), each pip move is worth USD 1.[U]
USD 0.25 per pip * [(10k units of EUR/USD)/(USD 1 per pip)] = 2,500 units of EUR/USD
So, Newbie Ned should put on 2,500 units of EUR/USD or less to stay within his risk comfort level with his current trade setup.

the paragraph is somehow confusing..lol...
Summarized of my understanding:
1) risk 1% of account size, with Account size USD 5,000, worst case u can lost USD50/trade
2) trade set-up: if the trade u going to enter having a 200pips SL then the maximum lot u can enter is 0.025 lot(2.5 micro lot) cuz 0.25USD*200=50USD
3) Lastly, the part "multiply the value per pip...with 10k units(1mini lot)..." is to calculate what lot size you should use, it is actually extra move cuz he already calculated that he can risk 0.25USD per pip which means 0.025lot
**minimum lot size ,most brokers offered is 0.01lot(1 micro lot/1000units), i not sure whether u can enter 0.025 or not.
*** this is a simple rule to start trading in LIVE, it is good cuz trade like this you wont get MarginCall while gaining experience
****For trade setup there still few things to remember other than trader's risk management, which is BASIC: leverage level, market hour, Support&Resistance & trend, DEEPER: indicators signal & Fundamental News~
Hope this will help~
