Your position size is an output, never a guess

Most people decide how much to buy first, and think about the loss later, if at all. They see a coin they like, punch in an amount that "feels right," and only when it's red do they wonder where to get out. That order of operations is exactly backwards, and it's the reason accounts blow up.

Risk-first sizing flips it. You decide the one number you can afford to lose before you decide anything else. Everything else (position size, leverage, target) is solved from that number. Your size becomes an output of your risk, not a feeling.

The one number that matters: 1R

Call your maximum acceptable loss on a single trade 1R, or one unit of risk. At BCI the default is a hard ₹200. That's the whole trade's downside, locked, before you place it. Not "around ₹200." Not "₹200 unless it really runs against me." Exactly ₹200, or you don't take the trade.

Risk defines size. Size does not define risk. Get that one sentence into your bones and half of trading discipline takes care of itself.

The method, worked end to end

Say you like SUI at $0.8528. You decide the setup is invalid if price closes below $0.8357, and that's your stop. The distance to your stop is:

• Stop distance = (0.8528 − 0.8357) / 0.8528 = ~2.0%

Now you don't ask "how many coins should I buy?" You ask: what position size makes a 2.0% move against me cost exactly ₹200?

• Notional = Risk ÷ Stop distance = ₹200 ÷ 0.020 = ₹10,000 (≈₹10,025 rounded to the tick)

That's it. A ₹10,025 position with a 2% stop loses ₹200 if you're wrong. If your stop were tighter, say 1%, the same ₹200 risk would let you hold a larger ₹20,000 position. Wider stop, smaller size. The risk stays nailed to ₹200 either way.

Leverage is a funding detail, not a risk lever

Notice leverage never entered the risk math. Leverage only decides how much margin you post to hold that ₹10,025. At 6.5× that's about ₹1,540 of collateral. It does not change how much you lose at your stop. Your stop does. People who "risk-manage" by lowering leverage while widening or ignoring their stop are fooling themselves. Set the stop, solve the size, and let leverage be plumbing.

Now the upside writes itself

Because 1R is fixed, every target becomes a clean multiple of it. A move to +2R on that SUI trade is roughly +₹390 after fees. You are risking ₹200 to make ₹390, which is nearly 2-to-1. You can be wrong more often than you're right and still come out ahead. That asymmetry, repeated with discipline, is the edge. Not the entry. The structure around the entry.

Why a machine should do this part

Under pressure, humans drift. The position that was supposed to risk ₹200 becomes ₹340 because the entry "filled a little worse" and you didn't re-solve. You move the stop down to give it "room." You add to a loser. Every one of those is the same failure: letting size drive risk instead of the reverse. BCI solves the size for you, every time, and refuses to let a single trade exceed your cap. Boring, mechanical, and exactly the point.
