Simple Layering EA that can copy a original entry lot size, TP, SL

I am seeking a programmer to develop a **Layering EA** for MT4 that automatically places additional trades above and below the original entry position.

The EA default should have the following function:

**Copy Stop Loss from the original trade ** - Any changes made to the Stop Loss on a single working order will be applied to all trades (both working and pending).
**Copy Take Profit from the original trade ** - Any changes made to the Take Profit on a single working order will be applied to all trades (both working and pending).
The EA should be able to start layering trades as soon as I entered, do not necessary needs TP or SL filled. I can edit any single working order there after and it can copy to all the trades (both working and pending)

While in the settings, these are the following
1. **Copy Lot Size from the original trade? (Yes/No)** - If "Yes," trades placed will be the same as the original entry.
2. **Double Down Lot Size from the original trade? (Yes/No)** - If "Yes," trades placed closer to the Take Profit will replicate the same lot size as the original trade, while trades closer to the Stop Loss will double the lot size.
3. **Custom Lot Size Nearer To TP? ** (if "No" is selected for both options above).
4. **Custom Lot Size Nearer To SL? ** (if "No" is selected for both options above).
5. **Distance between each layered trade?**.
6. **Cancel all pending orders if the Stop Loss or Take Profit is hit? (Yes/No)**.

### Example Scenario A:

If I initiate a **buy trade** on **XAUUSD** with the following details:

- **Entry**: Long @ 2740.50

- **Stop Loss (SL)**: 2735

- **Take Profit (TP)**: 2745.5

- **Lot Size**: 0.01

- **Distance between layered trades**: 100 pips

The EA will automatically place the following pending orders:

- **Buy Limit orders** at 2739.5, 2738.5, 2737.5, 2736.5, 2735.5

- **Buy Stop orders** at 2741.5, 2742.5, 2743.5, 2744.5

These additional trades can either replicate the original Stop Loss, Take Profit, and Lot Size or use custom settings based on the EA's configuration. Furthermore, the EA will cancel all pending orders if the original trade hits its Stop Loss or Take Profit, depending on the settings.

### Explanation of Point 6 (Double Down Lot Size):

If **Double Down Lot Size** is enabled, the lot sizes will adjust based on the proximity to the Stop Loss or Take Profit. For example:

Assume you have the same **buy trade**:

- **Entry**: Long @ 2740.50

- **SL**: 2735

- **TP**: 2745.5

- **Original Lot Size**: 0.01

The EA will place pending orders as follows:

- Trades closer to the **Take Profit** will maintain the same lot size as the original trade:

- Buy Stop @ 2744.5 with **Lot Size 0.01**

- Buy Stop @ 2743.5 with **Lot Size 0.01**

- Buy Stop @ 2742.5 with **Lot Size 0.01**

- Buy Stop @ 2741.5 with **Lot Size 0.01**

- Original Entry @ 2740.5 with **Lot Size 0.01**

- Buy Limit @ 2739.5 with **Lot Size 0.02**

- Buy Limit @ 2738.5 with **Lot Size 0.02**

- Buy Limit @ 2737.5 with **Lot Size 0.02**

- Buy Limit @ 2736.5 with **Lot Size 0.02**

- Buy Limit @ 2735.5 with **Lot Size 0.02**

In this case, the lot size for the trades closer to the Stop Loss will double.
