Definition: Put-call ratio (PCR) is an indicator commonly used to determine the mood of the options market. Being a contrarian indicator, the ratio looks at options buildup, helps traders understand whether a recent fall or rise in the market is excessive and if the time has come to take a contrarian call.

What happens at 72 C during PCR?
72⁰C is the optimum temperature for the Taq polymerase to build the complementary strand. It attaches to the primer and then adds DNA bases to the single strand one-by-one in the 5′ to 3′ direction. The result is a brand new strand of DNA and a double-stranded molecule of DNA.
What is PCR extension?
Steps of PCR – Extension. Extension is achieved by using the loosened nucleotides of each base to grow the complementary DNA strand. The end result is two double-stranded products of DNA. The temperature that is used during the extension phase is dependent on the DNA polymerase that is used.
What happens at 55 degrees in PCR? The primers cannot bind (anneal) to the strands of DNA at temperature of the denaturation, so the vial is cooled to 45-60 degrees C (Scheme – Annealing of the primers) . The final step of the reaction is elongation of the primers – the synthesis of new strands by making a complete copy of the templates.

Vega measures the amount of increase or decrease in an option premium based on a 1% change in implied volatility. Vega is a derivative of implied volatility. Implied volatility is defined as the market’s forecast of a likely movement in the underlying security.
Is higher implied volatility better? Options that have high levels of implied volatility will result in high-priced option premiums. Conversely, as the market’s expectations decrease, or demand for an option diminishes, implied volatility will decrease. Options containing lower levels of implied volatility will result in cheaper option prices.
