What a trade has to clear
Arithmetic, not opinion. It decides more than any pattern above does.
What this track is for
This track is about the arithmetic a trade has to clear. That arithmetic happens whether the chart is read well or badly. It covers what a round trip costs once the statutory charges are counted. Then the share of attempts that has to be right just to stand still. Then what taking more trades does to an average. Then why a fall and the rise that undoes it are different sizes. And finally, where quantity comes from.

The track, in order
5- The Charge Stack: What One Round Trip Actually CostsStart with the only figure that is certain in advance. Brokerage is one line of several. The statutory ones are charged whether the trade worked or not.A round trip is two transactions. Each one is charged. Brokerage is the line people quote. It is often the smallest. The statutory lines are set by rule, not by a broker. They are securities transaction tax, exchange transaction charges, the SEBI turnover fee, stamp duty, and the GST levied on top of some of those. They apply whether the trade worked or not. The total is small in rupees and large as a fraction of a small move.
- Break-Even Hit Rate: How Often You Have to Be Right to Stand StillNow turn that cost into a requirement. With equal wins and losses, the fraction you have to get right just to stand still is fixed by division. It climbs steeply as the target narrows.If wins and losses are the same size, and every trade costs the same to place, the fraction that must be right just to stand still is fixed by arithmetic. With no costs at all it is 50%. Every rupee of cost pushes it above 50%. The smaller the bracket, the harder it pushes. A cost equal to a fifth of the bracket needs 60%, a huge difference in how good a decision process has to be.
- Frequency Multiplies the Sign, Not the SizeThe obvious response to a hard requirement is more attempts. Here is what more attempts actually do. They multiply the average. They do not improve it.Twenty trades a day is not twenty chances to recover. Say the average trade has a negative expected value. Taking more of them makes the outcome more certain, not better. Frequency multiplies whatever sign the average carries. The same arithmetic is why a positive average is worth repeating. It is also why establishing the sign is the whole question. The number of trades is not.
- Drawdown Recovery: Why a 33% Loss Needs About a 49.3% GainThe other imbalance, and the one that decides whether a bad run is survivable. A 33% fall needs a 50% rise. The curve steepens all the way.A loss and the gain that undoes it are not the same size, because the gain is worked out on the smaller amount that is left. Lose 10% and you need 11.1% to get back. Lose 33% and you need about 49.3%. Lose 50% and you need 100%. The curve steepens the whole way. That is arithmetic rather than advice, and it is why the size of the worst loss matters more than the size of the average win.
- Size Follows the Level, Not the ViewClose with the one lever all of this leaves you. Quantity is not a measure of conviction. It falls out of the capital at risk and the distance to where the read is wrong.Quantity is a division, not a judgement. Decide what fraction of capital is acceptable to lose on one decision. Then decide the level at which the read would be wrong. The amount at risk divided by the distance to that level gives the quantity. Conviction does not appear anywhere in it. A stronger view does not change the arithmetic. It only changes how it feels to apply.
