  1. 0:00Let me ask you a question. Would you
  2. 0:01trade a strategy that loses 88% of the
  3. 0:04time? Because most traders would look at
  4. 0:05that strategy and say, "Absolutely
  5. 0:08not." And then give you the finger and
  6. 0:10say that's a terrible strategy. But what
  7. 0:12if I told you that strategy was
  8. 0:13profitable? And not theoretically
  9. 0:15profitable. I'm talking about the actual
  10. 0:17strategy I showed you yesterday. I
  11. 0:19analyzed 776 trades and only won about
  12. 0:2212% of the time. That means almost nine
  13. 0:24out of 10 trades were losers. And yet it
  14. 0:27made money. And I think this exposes one
  15. 0:29of the biggest understandings that
  16. 0:30traders have about win rate. Because
  17. 0:33we're obsessed with being right. 50% win
  18. 0:35rate, 60% win rate, 70%. You'll see
  19. 0:38people advertising strategies with an 80
  20. 0:40or 90% win rate. But without knowing one
  21. 0:42specific number, the win rate tells you
  22. 0:45basically nothing. That number is your
  23. 0:47risk to reward ratio. Let me show you
  24. 0:49something really simple. Let's ignore
  25. 0:51spreads, commissions, and slippage for a
  26. 0:53second just to make it mathematically
  27. 0:54clean. Every time I lose $100 and every
  28. 0:58time I make $100, that's a one-to-one
  29. 1:01risk to reward ratio. I need to win 50%
  30. 1:04of my trades just to break even. But
  31. 1:06watch what happens when my winners
  32. 1:07become larger than my losers. If I have
  33. 1:10a one-to-1.5, it's 40%. If I have a
  34. 1:12one-to-two, it's 33%. A one-to-three is
  35. 1:1625%, a one-to-four is 20%, a one-to-five
  36. 1:20is 16%, and a one-to-10 risk to reward
  37. 1:23ratio needs 9% to break even. Think
  38. 1:27about that last one. With a one-to-10
  39. 1:29risk to reward ratio, theoretically I
  40. 1:31could lose more than 90% of my trades
  41. 1:34and still be break even. Obviously, real
  42. 1:36trading has costs, execution
  43. 1:38differences, slippage, and all the other
  44. 1:40[ __ ] But mathematically, that's how
  45. 1:42powerful the relationship between win
  46. 1:44rate and risk to reward ratio actually
  47. 1:47is. And yesterday's strategy gave us a
  48. 1:49real-life example. The average winner
  49. 1:51was roughly nine to 10 times larger than
  50. 1:54the average loser. So the average
  51. 1:55historical break even rate is around 9%
  52. 1:57to 10% and the actual win rate was 12%
  53. 2:01and that's an edge. Not a high win rate,
  54. 2:04but the fact that when the strategy
  55. 2:06actually catches some winners, that
  56. 2:07winner pays off for a pile of losers.
  57. 2:10But, there's another problem here
  58. 2:12because when I say a 12% win rate, you
  59. 2:14might subconsciously imagine the winners
  60. 2:16being evenly distributed. Nine losers,
  61. 2:19one winner. Nine losers, one winner.
  62. 2:22Nice and orderly. But, that's not how
  63. 2:24probability works. And the exact same
  64. 2:27misunderstanding happens with a 50% win
  65. 2:29rate strategy. If I tell you a strategy
  66. 2:31wins 50% of the time, your brain wants
  67. 2:33to imagine one winner, one loss. One
  68. 2:36winner, one loss. Or maybe two
  69. 2:38back-to-back losers and two back-to-back
  70. 2:40winners. And that over time everything
  71. 2:42stays balanced. But, 50% doesn't mean
  72. 2:45that at all. It means that over a
  73. 2:46sufficiently large sample, approximately
  74. 2:49half of the observations were winners.
  75. 2:51The order of those winners and losers
  76. 2:53can be absolutely brutal. You can have
  77. 2:5510 losers in a row, three winners,
  78. 2:57another six losses, five winners, and
  79. 3:00another nine losses. And eventually over
  80. 3:02hundreds or thousands of trades,
  81. 3:04everything averages out towards the
  82. 3:06strategy's underlying win rate, the 50%.
  83. 3:09And that's where trading stops being a
  84. 3:10math problem and becomes a human
  85. 3:12problem. Think about flipping a coin.
  86. 3:14Heads and tails are each 50%, but nobody
  87. 3:16expects heads, tails, heads, tails,
  88. 3:18heads, tails. And especially not
  89. 3:20indefinitely. You could easily get
  90. 3:22several heads in a row. That doesn't
  91. 3:24suddenly mean the coin stopped being
  92. 3:2650/50. And trading results behave the
  93. 3:28same way. Except there's one enormous
  94. 3:30difference. Money is attached to the
  95. 3:32outcome. So, after enough consecutive
  96. 3:34losses, you don't calmly say, "Well,
  97. 3:37this is perfectly compatible with the
  98. 3:38statistics and variables." You say this
  99. 3:41strategy doesn't [ __ ] work anymore.
  100. 3:43And then you change it. And that's where
  101. 3:44traders destroy themselves. Our real
  102. 3:47data showed this exactly in yesterday's
  103. 3:50video. Across the unrestricted test, we
  104. 3:52found a historical losing streak of
  105. 3:54approximately 47 trades. 47. Think about
  106. 3:58actually experiencing that in your
  107. 4:00trading. Not looking at a spreadsheet
  108. 4:02after the fact, you're actually trading
  109. 4:04it. Loss number 10, loss number 15, loss
  110. 4:07number 20. At some point, you're opening
  111. 4:09TradingView and thinking, "Something's
  112. 4:11changed." Then trade number 30 is a
  113. 4:13loss. Now you're changing settings,
  114. 4:16you're adding indicators, you're
  115. 4:17adjusting the stop loss. Maybe you stop
  116. 4:20trading altogether, and then eventually,
  117. 4:22a huge winner appears. Except you don't
  118. 4:24take it, because you lost the previous
  119. 4:2630 trades convinced that your strategy
  120. 4:28was broken. And on a strategy designed
  121. 4:30for massive winners, missing that one
  122. 4:32trade can destroy the entire
  123. 4:35mathematical expectancy. That's the
  124. 4:37irony. The trader didn't necessarily
  125. 4:39lose because the strategy stopped
  126. 4:41working. They lost because they couldn't
  127. 4:43emotionally survive the distribution of
  128. 4:45returns required for the strategy to
  129. 4:47work. And this brings me to something
  130. 4:48else that I think traders massively
  131. 4:50underestimate: time. Let's say we
  132. 4:52genuinely identified a strategy with a
  133. 4:54positive expectancy. Not something we
  134. 4:56curve fitted yesterday. A strategy we've
  135. 4:58tested properly and have reasonable
  136. 5:00evidence that it contains an edge. That
  137. 5:02does not mean it's going to make money
  138. 5:04tomorrow. It doesn't necessarily mean
  139. 5:06it'll make money next week. It might not
  140. 5:08even make money next month. An edge
  141. 5:10reveals itself across a distribution of
  142. 5:13trades. The larger the sample becomes,
  143. 5:15the more opportunity mathematical
  144. 5:17advantage has to express itself. two
  145. 5:20traders running the exact same
  146. 5:21profitable strategy. Trader A trades it
  147. 5:24for 3 months. He gets a horrible
  148. 5:26sequence, drawdown, losses, a couple of
  149. 5:29winners, more losses. He quits. He says,
  150. 5:32"Strategy doesn't work." Trader B trades
  151. 5:34the same strategy with appropriate risk,
  152. 5:37follows it consistently for 3 years. He
  153. 5:40experiences good months, bad months,
  154. 5:43winning streaks, losing streaks, periods
  155. 5:45where it feels amazing, and periods
  156. 5:47where it feels completely broken. But,
  157. 5:49assuming the edge actually persists, his
  158. 5:52much larger sample gives that expectancy
  159. 5:54far more opportunity to emerge. And
  160. 5:57that's why saying if it has an edge 3
  161. 5:59years guarantees profit would actually
  162. 6:01be wrong, cuz there's no guarantees. The
  163. 6:04better way to say it is, the longer you
  164. 6:06execute a genuine positive expectancy
  165. 6:09strategy consistently, the more
  166. 6:12opportunity you give the edge to
  167. 6:13overcome short-term randomness. That's a
  168. 6:16massive distinction, but we have to be
  169. 6:18hyper definitive. The definition of the
  170. 6:21terms that you use matters. Expectancy
  171. 6:24is what actually matters. This is why
  172. 6:26professional thinking isn't how often am
  173. 6:29I right? It's what happens when I'm
  174. 6:31right versus what happens when I'm
  175. 6:33wrong. Imagine trader A wins 70% of the
  176. 6:36time. That sounds amazing. He risks
  177. 6:38$100, and when he wins, he makes $50.
  178. 6:42When he loses, it's 100 bucks. Over 100
  179. 6:45trades, 70 winners * $50 is $3,500.
  180. 6:5030 losers * $100 is $3,000.
  181. 6:54He only made $500 before trading costs.
  182. 6:57Now, imagine trader B only wins 30% of
  183. 7:00the time. And that sounds terrible. Same
  184. 7:03$100 risk, but winners make him $300.
  185. 7:0730 winners, $300, nine grand. 70 losers,
  186. 7:11$100, $7,000.
  187. 7:14Net result, he's up $2,000.
  188. 7:17The trader who was wrong 70% of the time
  189. 7:20made more money using this
  190. 7:22oversimplified example. That's why
  191. 7:24asking, "What's the win rate?" without
  192. 7:26asking, "What's the average winner
  193. 7:28versus average loser?" is almost
  194. 7:30meaningless. But, there's a catch.
  195. 7:32Before everyone runs over to TradingView
  196. 7:34and changes their take profit to 10
  197. 7:36times their stop loss, please don't do
  198. 7:38that. That's not what I'm saying. You
  199. 7:39can't manufacture an edge by arbitrarily
  200. 7:42increasing your target because as you
  201. 7:44move your target further away, your
  202. 7:45probability of reaching it generally
  203. 7:47goes down. The goal isn't maximum risk
  204. 7:49to reward and it isn't maximum win rate.
  205. 7:52It's finding a combination where the
  206. 7:53probability of winning and the magnitude
  207. 7:55of those wins produces positive
  208. 7:57expectancy after cost of trading. And
  209. 7:59then comes the hard part. Finding
  210. 8:01something mathematically profitable is
  211. 8:03one problem, but being psychologically
  212. 8:05capable of trading it is another.
  213. 8:08Personally, I think this is something
  214. 8:09traders should consider much more
  215. 8:11seriously. Two strategies can have
  216. 8:13identical long-term profitability and
  217. 8:15one might be completely impossible for
  218. 8:17you to trade. One trader might happily
  219. 8:18take tiny losses for weeks waiting for
  220. 8:20that one monster trade. Another trader
  221. 8:23could go insane after eight consecutive
  222. 8:25losses. That person might perform much
  223. 8:27better with higher win rate, lower
  224. 8:29reward system. Neither of them is
  225. 8:31automatically better than the other. The
  226. 8:33best strategy isn't simply the one that
  227. 8:35has the prettiest backtest. It's the one
  228. 8:37with the edge that you, personally, can
  229. 8:40actually continue executing when the
  230. 8:42distribution becomes uncomfortable
  231. 8:44because the market doesn't care that
  232. 8:45you're frustrated. It doesn't know that
  233. 8:47you lost 10 times in a row. And trade
  234. 8:49number 11 doesn't become a winner simply
  235. 8:51because you deserve one. And I think
  236. 8:52this is one of the biggest lessons from
  237. 8:54the data we've been analyzing over the
  238. 8:55last couple of days. AI helps me find
  239. 8:57patterns in hundreds of trades extremely
  240. 8:59quickly, but the numbers expose
  241. 9:01something much more interesting than
  242. 9:02which day of the week performs best.
  243. 9:04They show just how psychologically
  244. 9:06difficult the mathematical variable
  245. 9:08strategy can actually be to trade. I
  246. 9:10don't think I could handle 47 losses in
  247. 9:12a row. A strategy that can lose 88% of
  248. 9:15its trades with disgusting losing
  249. 9:17streaks. It would literally make you
  250. 9:19feel like an idiot if you were to
  251. 9:21continue trading it. How are you
  252. 9:22supposed to keep that idea in the back
  253. 9:23of your head knowing that this has a
  254. 9:25positive expectancy? Meanwhile, there
  255. 9:27could be another strategy that has a 70%
  256. 9:30win rate and you feel like a genius
  257. 9:31because of it, at least 70% of the time,
  258. 9:34but it barely makes any money. So, stop
  259. 9:36asking only, "What's the win rate. Start
  260. 9:38asking what's my average winner, what's
  261. 9:41my average loser, and what's my
  262. 9:42expectancy. What's the historical
  263. 9:44drawdown, and what's my biggest losing
  264. 9:47streak, and can I deal with that
  265. 9:48emotionally? This is why it's so
  266. 9:50difficult for me to suggest a specific
  267. 9:53strategy that's good for everyone,
  268. 9:56because everyone has their own risk
  269. 9:58tolerance. And I know a majority of
  270. 10:00traders fall in the bucket of couldn't
  271. 10:02take 47 back-to-back losses. I
