Sizing and break-even for the BEL breakout

In Playbook 15.1 the fill was ₹460.46 and the initial stop ₹428.20. (a) Find the number of shares $Q$ under the 1% rule and the rupee value of $1R$. (b) The position was sold at ₹430.94. Compute the total round-trip costs, line by line. (c) Express the costs as a fraction $c$ of $1R$, and find the break-even win rate $p^*$ of M04 Proposition 4.5 for an average winner of $W = 2.5R$ (costs only, no slippage). (d) With $p = 0.35$, $W = 2.5$ and the same $c$, what is the expectancy per trade? Explain why this number cannot be taken from the playbook's data.
