Stop-loss an stop-win
A stop rule a di one part a a “system” weh have a real effect, cause it change ow much yuh bet.

Fi stop early cut di total amount yuh bet, an suh it cut di expected loss. It nuh mek no edge; a stop-win nuh “lock in” nutten weh di nex spin couldn’t gi or tek.
Stop-loss
Fix di amount yuh ready fi lose an lef wen it done. It put a cap pon di worst case, end di session bifo di chasin start, an mek yuh able fi work out di expected cost a di evenin: neva more dan di stop-lossstrategy demStop-lossA amount a loss weh yuh set fram bifo, an wen yuh reach it yuh end di session (di loss weh mek yuh stop).Read di whole ting →, usually less. Outta all di rule dem pon dis site, a dis one change wah happen to a playa di most reliable, cause a di only one weh reliably end a session.
Stop-win

Di nex spin did always a go be 18/37, nuh care if yuh play it tonight or nex week.
A ole argument
People a argue fi a long time bout if fi quit while yuh ahead help. Di logician John Venn did hold seh a playa weh alone can choose wen fi stop have di advantage, as long as credit nuh have no limit. Lord Rayleigh ansa seh wid fortune weh have a end pon both side, di advantage disappear, an di modern theorem dem agree: no rule bout wen fi stop nuh change di average result fi evry unitmoney mattaUnitDi base stake weh a system or a playa work wid. Dem describe progression inna unit suh dem work at any table.Read di whole ting → yuh stake (Epstein, 2013). French have a phrase fi lef di table while yuh ahead, faire Charlemagne. It name a habit, not a edge.

Wah mek di average get betta
Not cause di stop find a good moment fi lef. Cause a session weh end afta 60 spin bet 60 stake instead a 100 an pay 2.70% pon less dolla.

Di rule bout di rule dem
A stop rule only work if yuh decide it bifo di session an nuh change it inna di middle. “Jus one more spin fi get back even” a di stop-loss a get renegotiate by di same smaddy it did mek fi protec. If yuh see dat a happen, lower di stake instead a raise di limit.
Question dem
