...automated strategy on Fyers. The core logic must follow Line Break chart rules—no other indicators—so every entry and exit will be driven strictly by the block changes those charts create. I need the Python code that translates that logic into live orders for both buying and selling legs of the spread. Here’s what matters most to me: • A clean, well-commented Python script that connects to the Fyers API and places the debit-spread orders automatically. • Parameters (strike distance, quantity, Line Break reversal size, time filters, etc.) exposed in one place so I can tweak them without digging through the code. • Robust error handling and position tracking so the script knows exactly when a leg is open, closed, or needs adjustment. If you ...

I need a developer who already knows their way around the Android Enterprise API to wire it into our existing Android application so that we can take full control of company-owned devices. The end goal is straightforward: once your work is in place, IT should be able to enroll a new handset in seconds and push or update policies on demand—no manual tweaking, no sideloaded scripts. The focus is squarely on two areas: • Device enrollment – the app must trigger zero-touch or QR-based enrollment flows, register the device with our backend, and confirm that the management profile is active. • Policy enforcement – from lock-screen rules to app-install restrictions, every policy needs to sync reliably with Google’s management framework and report statu...

...core idea is to interact with one or more Telegram channels in an automated fashion rather than with private chats or groups. I’ll share the exact workflow once we start, but it will involve monitoring messages in real time, triggering actions based on simple rules, and handling any required log-in or 2-FA steps programmatically. Direct use of the Telegram Web interface is preferred over the Bot API so that we keep full parity with human users. Deliverable • A clean, well-commented script or small project folder that I can run from the command line on Windows or Linux. • A short README explaining prerequisites, environment variables, and how to launch the script. • Clear pointers in the code where I can adjust channel IDs, keywords, or logic as my need...

...hockey league that ties seamlessly into the platforms our players already use. All users must authenticate through Discord OAuth, then verify themselves by linking an Xbox Live or Playstation Network account. Once inside, the site will surface real-time player, team, and league statistics that I will supply through an external data source (populated Google Sheet spreadsheet cells from third-party API); your job is to pull, cache when sensible, and display that data in an attractive, responsive front end. Two permission-based back-office areas complete the build: Team Management Portal This area is visible only to authorised team staff and must include: • Roster management (add, release, or trade players) • Player performance tracking drawn from the same stats fe...

...at the kernel level specifically how it detects unauthorized or suspicious kernel modules and to derive practical recommendations for safely loading a driver in such an environment. Importantly, this is not a full reverse engineering of the entire driver. The scope is limited to identifying the specific detection mechanisms the anti-cheat driver uses to scan the kernel, focusing on the Windows API calls and kernel structures it interrogates. The goal is to determine what traces a manually loaded driver leaves behind and how to avoid detection by cleaning or spoofing those traces appropriately. The analysis will examine how the anti-cheat driver enumerates loaded kernel modules and inspects key system structures, including: PiDDBCacheTable – how it verifies loaded driver ...

...Microsoft Dynamics 365 Business Central through the standard API. The model works, but the scheduled refresh now fails with frequent time-outs; reliability is my biggest concern. So far I have: • enabled incremental refresh on the largest tables • tuned a handful of queries • experimented with splitting data into smaller API calls None of these measures has eliminated the failure. I need an expert who can: 1. pinpoint the exact bottleneck within the current data model, gateway settings, or API calls 2. redesign the retrieval strategy so the report finishes every refresh window without timing out 3. leave me with a clean, documented PBIX (or dataflow) that follows best practice for query folding, partitioning, and Business Central API limits. ...

I run , a portal that already generates and corrects PAN cards, and I’m ready to open up the underlying service as a commercial API. I need a specialist who can turn the existing internal endpoints into well-structured public documentation and design a straightforward pay-as-you-go user plan. The documentation must live inside my portal, look professional on both desktop and mobile, and cover everything a developer needs to get productive fast: every endpoint and method, detailed error codes with handling advice, plus the rate limits and quota rules that match the plan you help me define. Authentication will be handled through API keys only, so the docs should include key creation, usage and rotation guidelines. For the user plan, I want a single pay-as-you-go model t...

...specify exactly how much of my balance I am willing to risk, then sizes and fires the order in real-time—no more, no less. Primary exchange focus is Mexc, with Bybit and Binance immediately after (xbt support can follow the same interface). The bot can run as a lightweight desktop app or CLI, I am happy with Python, Node, or Rust under the hood as long as it speaks each exchange’s REST & WebSocket API and keeps execution times under 200 ms. Core workflow • I enter the trading pair, my stop-loss price, and the % of balance of my account I want to risk. • The tool pulls the live mark/last price, calculates the exact position size, and places either a market or limit order (my choice each time). • If price hits the stop level the loss never exc...

I need to add real–time Australian driver’s-license verification to my existing VOIP platform immediately. Callers will enter or speak their licence details during the call flow; the system must then query the official Australian DVS (or a comparable API you recommend) and return an instant pass/fail result before the call proceeds. The only document we will accept is a Driver's License, so the solution should extract and validate all standard licence fields—name, address, date of birth, licence number and expiry—while logging a full audit trail for compliance. I am flexible on the underlying VOIP stack, provided the final workflow runs smoothly on my current hosted instance and is maintainable in-house after hand-over. Deliverables • Fully ...

Below is a list of the most common API calls you would use. This isn't an exhaustive list, and you might not use every call listed below. For example, you would use OF01 or OF24 to send offers, not both. Offers: OF01 (POST): Send an XLSX/CSV/XML file - allows for only sku and quantity in the file. Best for automating inventory and set price/other fields manually OF24 (POST): Allows for writing all offer data directly into the API call instead of a file. ALL required offer fields need to be filled out Orders: OR11 (GET): Pull orders into your system OR21 (PUT): Accept or refuse orders OR23 (PUT): Create/update tracking/shipment information. One order per call or one tracking link per order (one package) OR24 (PUT): Confirm the shipment if you used OR23 to add tra...

...updates should come from a standard crypto market API (CoinGecko, CoinMarketCap, etc.), but keep the logic abstract enough so I can swap feeds later without rewriting the front end. I already have endpoints that return my wallet balances in JSON, so the chart just needs to consume that feed, merge it with live prices, and display: • A time-series line chart of portfolio value • A current allocation pie or doughnut chart • Percentage change badges for 24 h, 7 d, and 30 d Deliverables 1. Front-end chart module (React, Vue, or vanilla JS with / D3 / Highcharts—your call, just note it clearly) 2. Embed snippet and step-by-step integration guide for my existing site 3.

...something lean that gets the numbers right every pay cycle. Here’s what I have in mind: • Core task: pull basic employee data (name, gross pay, filing status, allowances, any pre-tax or post-tax deductions) and return precise federal, state, and local withholding figures. • I’d like the calculations to follow the current IRS tables automatically; if you prefer plugging in a lookup file or an API, that works as long as it stays up to date. • The output should be easy to export—CSV or an Excel sheet is fine—so I can drop the figures straight into my accounting software later. • A small dashboard or at least a clear command-line summary that flags anomalies (negative net pay, unusually high deductions, etc.) would be a plus. Del...

I have a JavaScript API guide written in a light, conversational style. Before it goes live I need a careful read-through of the Introduction section to catch every grammar, spelling, and punctuation slip while keeping the friendly tone intact. You’ll work directly in the Markdown file (or a Google Doc if you prefer), make the necessary edits, and flag any sentence that might read awkwardly after correction. No need to touch examples, code snippets, or layout—this task is strictly language polishing for that one section. Deliverable: • A clean, corrected Introduction ready to drop into the documentation, plus a version with tracked changes so I can review what was adjusted. If you have a sharp editorial eye and are comfortable with developer-facing content, I&rs...

I’m in the middle of revamping our JavaScript API reference, but the documentation is still incomplete. Every public-facing function has to be documented with a clear, thorough description and at least one concise code example that shows typical usage. One-liners won’t cut it—I need detailed explanations that spell out what the method does, why a developer would call it, and any nuances they should watch for. You’ll work directly in the existing markdown files (or JSDoc comments if you prefer) so the finished material fits seamlessly with what’s already there. Technical accuracy and a friendly, developer-oriented tone are both essential. Deliverables • Updated documentation covering every exposed function • For each function: purpose, ...
