The contents of this paper may or may not related directly to the paper arXiv:2512.15720, its freestyle. And also im using a simple 2-states with 20 sample data rather than 15-states with many data as what said on the paper, just to keep things simpler.

Lets try breaking down how to multiply the matrix by itself using power rule, given:

\[

becomes $P$ into $P^2$, therefore:

\[

then we calculate for the entropy of each row by following the general equation

\[

If this equation is from a paper rooted in Physics (Statistical Mechanics), Mathematics, or Pure Statistics, the base is typically the natural logarithm, base $e$. Therefore,
|
| 387 |

|
| 388 |
+
\[

\begin{align*}

therefore:

|
| 452 |

|
| 453 |

in here, we have $K = 2$ becuase we have buy or sell as states,$K$ refers to the total number of posssible states hence
|
| 454 |

\begin{align*}
|
| 455 |

H_t &:= -\frac{1}{\log K}(\textcolor{red}{-0.5691094329}) \\

|
| 459 |
+
\end{align*}
|
| 460 |
+
|
| 461 |
+
the paper says high entropy inficates unpredictable transitions, meanwhile low entropy indicates structure
|
| 462 |
+
|
| 463 |
+
\begin{align*}
|
| 464 |

this values depend on the creator, but the paper saus 0.05 amd 0.95 as treshold to trigger possitions.
|
| 469 |
+
|
| 470 |
+
the paper has 3 criteria before entering a trade,
|
| 471 |
+
one,
|
| 472 |
+
|
| 473 |
+
\[
|
| 474 |
+
H_t < H_{5th percentile}
|
| 475 |
+
\]
|
| 476 |
+
two,
|
| 477 |
+
|
| 478 |
+
\[
|
| 479 |
+
V_t > V_{95th percentile}
|
| 480 |
+
\]
|
| 481 |
+
|
| 482 |
+
three,
|
| 483 |
+
|
| 484 |
+
\[
|
| 485 |
+
5 bps \leq |trailing^{5min}_{return}| \leq 20 bps
|
| 486 |
+
\]
|
| 487 |
+
|
| 488 |
+
and after all conditions is met, he enters a trade
|
| 489 |
+
|
| 490 |
+
\[
|
| 491 |
+
Direction = sgn(trailing_5min_return), \quad +1 = buy ; -1 = sell
|
| 492 |
+
\]
|
| 493 |
+
|
| 494 |
+
and after entry, he places a stoploss
|
| 495 |
+
\[
|
| 496 |
+
stoploss = entry^{price} \pm 5bps
|
| 497 |
+
\]
|
| 498 |
+
|
| 499 |
+
then takeprofit
|
| 500 |
+
\[
|
| 501 |
+
Take-Profit = Entry Price ± TP_threshold
|
| 502 |
+
\]
|
| 503 |
+
|
| 504 |
+
and emergency exit
|
| 505 |
+
|
| 506 |
+
\[
|
| 507 |
+
Max hold time = 300 seconds (5 minutes)
|
| 508 |
+
\]

\section{failed attempt}
|
| 511 |
+
at first, i actually tried manually recreating the paper using 15-state transition matrix markov chain model but in the long run i found out the formula is general and applicable to any given number of state hence i used simpler 2-state model
