Box Grid Plan Generator
A grid inside a box makes money one step at a time and loses it all at once. Enter the box, the step, the lot per level, the tick value and your account, and the generator writes the whole ladder: every buy level, the lots you'll be holding there, the open drawdown if price sits there, the take-profit for each rung, and the kill switch past the box where you cut everything. Drawdown at level k follows the triangle number, step × k(k−1)/2 per lot, which is why a grid that looks harmless at 3 levels is lethal at 12. Written for a long grid off the box low; flip the side for a short grid off the high.
Each rung takes profit 1 step back toward the middle. The first rung sits 1 step inside the far edge from the middle, so the grid covers the half of the box you fade.

Enter the box, the step and the sizing, then hit Write. Or load an example to see a grid that survives next to one that doesn't.
How it builds the ladder. The grid covers the half of the box between the midpoint and the edge you fade. Rungs sit every step from 1 step below the midpoint down to the box low (mirror for a short grid). Rung k holds k lots. Open drawdown at rung k = step × k(k−1)/2 × lots × value per point, where value per point = value per tick / tick size. Take-profit for each rung is 1 step back toward the middle, so 1 completed cycle earns step × lot × value per point. The kill switch sits the chosen % of the box beyond the edge; at the kill switch you hold every rung and the loss is the full-ladder drawdown plus every lot times the kill distance. Worst case = that loss as % of the account. Under 10% is a grid that survives, 10% to 25% is one breakout from a bad month, over 25% is a grid the box owns. Cycles to repay = kill loss / profit per cycle. Keyboard: Enter writes, 1 to 3 load the examples.
Educational tool only, not financial advice. A grid has no edge of its own; it borrows one from the box holding. The ladder tells you the price of being wrong about that. Pay attention to the cycles-to-repay number before the step size.
