Which tool when?

Before the trade: pick your stop where the idea is wrong, then use the position size calculator (or the crypto version for leverage) so a stop-out costs exactly what you planned. Check the target with the risk reward calculator — is the RR worth it at your win rate?

After the trade: log it in the trading journal template or in Profit Prism Journal, and review weekly which setups and habits make or cost you money.

Do it all in one place

Profit Prism Journal sizes, logs and scores every trade in R, with strategy stats, a calendar, loss limits and money-leak reports. Try it free for 7 days, no card.
