# MADBTCUSD SSS

### MADBTCUSD Endeksi Nasıl Hesaplanır?

MADBTCUSD aşağıdaki formüle göre hesaplanır:

**MADBTCUSD Endeksi**

$$
\begin{align\*}
\text{drift} &= \left( \frac{\text{btcCurrentPrice} - 1}{\text{btcLastSecondPrice}} \right) \times 5 \\
\\
\sigma &= \frac{\text{expectedvol}}{\sqrt{3600 \times 24 \times 365}} \\
\\
norm &= \text{norminv}(\text{Random}, 0, 1) \\
\\
S\_{n+1} &= S\_{n} \times e^{\left\[\left(\text{drift} - \frac{\sigma^2}{2}\right) \times \text{dt} + \sigma \times \sqrt{\text{dt}} \times norm\right]}
\end{align\*}
$$

burada:

* Başlangıç Sn=1000
* dt=1
* beklenen vol：%100 (beklenen vol, MADBTC'nin beklenen zaman volatilitesidir)
* "**Rastgele sayı**", **8 ondalık basamak hassasiyetiyle mevcut BTC fiyatı** temel alınarak hesaplanır

**Rastgele Sayının Hesaplanması:**

```python
import hashlib
from decimal import Decimal

# Bitcoin'in mevcut fiyatının 48923.56789101 olduğunu varsay
bitcoin_price = Decimal("48923.56789101")

# Bitcoin fiyatının SHA-256 hash değerini hesapla
price_hash = hashlib.sha256(str(bitcoin_price).encode('utf-8')).hexdigest()

# Hash'ten ilk 8 onaltılık sayıyı çıkar
hash_substring = price_hash[:8]

# Onaltılık dizeyi tam sayıya dönüştür
hash_integer = int(hash_substring, 16)

# Rastgele bir sayı elde etmek için tam sayıyı 4294967296'ya böl
# (FFFFFFFF onaltılık sayısına karşılık gelen onluk sayı)
random_number = hash_integer / 4294967296
# Rastgele sayıyı yazdır
print(random_number)
```

Belirlenen rastgele sayı 0 ise yeniden hesaplanır

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pancakeswap.finance/turkish/ticaret/perpetual-trading/perpetual-trading-v2/madbtcusd/madbtcusd-faq.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
