In F&amp;O, it works similarly but there are a few things specific to derivatives that are worth understanding.<\/p>\n\n\n\n<p><strong>What is the buy average in F&amp;O?<\/strong><\/p>\n\n\n\n<p>Buy average in F&amp;O is the average price at which you have entered a position across multiple trades in the same contract. It is calculated the same way as in equity:<\/p>\n\n\n\n<p><strong>Buy average = Total amount spent \u00f7 Total quantity bought<\/strong><\/p>\n\n\n\n<p>For example, if you buy 50 lots of Nifty futures at 22,000 and then buy another 50 lots at 22,200, your buy average is:<\/p>\n\n\n\n<ul><li>Total amount = (50 \u00d7 22,000) + (50 \u00d7 22,200) = 11,00,000 + 11,10,000 = 22,10,000<\/li><li>Total quantity = 100 lots<\/li><li>Buy average = 22,10,000 \u00f7 100 = <strong>22,100<\/strong><\/li><\/ul>\n\n\n\n<p><strong>How is it different in F&amp;O?<\/strong><\/p>\n\n\n\n<p>In equity, you can hold a stock indefinitely and keep averaging your buy price over time. In F&amp;O, every contract has an expiry date. Once the contract expires, your position is settled and the buy average resets for the next contract.<\/p>\n\n\n\n<p>Also, in F&amp;O your buy average only reflects the entry price of the contract, it does not include the margin blocked or the brokerage and charges paid.<\/p>\n\n\n\n<p><strong>What about options?<\/strong><\/p>\n\n\n\n<p>For options, the buy average works the same way it is the average premium you paid across multiple buy trades in the same option contract.<\/p>\n\n\n\n<p>For example, if you buy 1 lot of Nifty 22,200 CE at a premium of \u20b9100 and then buy another lot at \u20b9150, your buy average premium is \u20b9125.<\/p>\n\n\n\n<p>Your profit or loss on the position is then calculated based on the difference between this average premium and the current premium of the option.<\/p>\n","protected":false},"author":65,"comment_status":"open","ping_status":"closed","template":"","format":"standard","meta":[],"ht_kb_category":[2849],"ht_kb_tag":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/ht_kb\/26179"}],"collection":[{"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/ht_kb"}],"about":[{"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/types\/ht_kb"}],"author":[{"embeddable":true,"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/users\/65"}],"replies":[{"embeddable":true,"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/comments?post=26179"}],"version-history":[{"count":1,"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/ht_kb\/26179\/revisions"}],"predecessor-version":[{"id":26181,"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/ht_kb\/26179\/revisions\/26181"}],"wp:attachment":[{"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/media?parent=26179"}],"wp:term":[{"taxonomy":"ht_kb_category","embeddable":true,"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/ht_kb_category?post=26179"},{"taxonomy":"ht_kb_tag","embeddable":true,"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/ht_kb_tag?post=26179"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
