Understand the number.
Then make the decision.
No stock picks or market predictions. Just clear explanations, worked examples and the assumptions behind a deliberate trade plan.
Position sizing with a stop loss and cash limit
A worked example showing why the smallest of three limits is the only share count that fits the whole plan.
Why is my position size larger than my account?
A tight stop can imply a surprisingly large notional position. That does not create extra buying power.
Risk per trade is not position size
Risking $250 and investing $250 are very different decisions. Understand risk, notional exposure and full loss.
Risk reward ratio after commissions and slippage
Compare gross and net R:R in the same trade, with explicit costs on both entry and exit.
Stock break-even price after fees
Your entry price is not necessarily your break-even. Reverse the cash-flow equation for fixed and percentage costs.
Stop-loss position sizing and gap risk
A stop price is a planning input, not a maximum-loss guarantee. See how an opening gap changes the math.
