Good day, I would like to build an automated trading system for Ninjatrader using 2 MACD, a Supertrend, and a moving average indicator. I want the option to adjust the indicator settings, the ability to trade at three different times, and the option to receive alerts. I want to get an idea of what that will cost me.

The system is designed for high-precision entries by filtering market noise and spikes. Key Requirements: •

✅ *Step-by-Step Strategy to Code – CRT + CISD (MT5 EA)* 🔧 *System Setup* *Timeframes Used:* - *D1* – Bias & CRT zones (High & Low) - *H1* – Confirm candle closes back inside CRT levels - *M5* – CISD pattern (entry trigger) --- 🟢 *Buy Setup – Logic* 1. *Detect D1 CRT Zone:* - Identify current day’s *High and Low* → define CRT levels. 2. *Wait for Sweep:* - Price must *break below D1 CRT Low* (wick). 3. *H1

I asked ChatGPT to come up with a strategy to trade the downside of gold. I'm looking for someone who can tell me whether the suggestion is feasible and, if not, how the scope and purpose of the paper can be achieved differently. At the end, a corresponding code should be created. Thank you for your feedback

I have a perfectly working EA that always gets altered, I need special security features implemented, and I already have a great idea of what I need. Super easy, codes already work, just need tweaking here and there. Cybersecurity proficiency would be a positive
