Develop EA with entry stop loss and immediate trailing (micro-scalping logic)

I am looking for an experienced MQL4/MQL5 developer to build an Expert Advisor with the following specific behavior:

• Place buy and sell orders with entry price equal to the stop loss

• Stop loss should trigger immediately when the trade goes into a small loss
• Trailing stop should activate immediately once the trade is in profit
• Designed for micro-scalping (very small price movements)
• Proper handling of spread, slippage, and execution

The EA should be placing both buy and sell orders where the entry price appears to be to the stop loss level. Despite this, some trades still close with small profits, while others close with small losses.

Stoploss and trailing

• The stop loss is automatically triggered as soon as the trade goes into a small loss.

• A trailing stop appears to become active immediately once the trade goes into profit.

From a technical perspective, this behavior could be explained by the following factors:

1. Bid/Ask spread differences

Even if entry and stop loss appear identical, Bid/Ask pricing means the effective trigger levels are different, which can result in small profits or losses.

2. Execution latency and timing

There may be a short delay between order execution and stop loss placement. During this window, price movement can cause small P/L before the stop loss is fully active.

3. Slippage (positive or negative)

Orders and stop losses can be filled at slightly different prices, which may result in small unexpected gains or losses.

4. Price rounding / point differences

What appears to be the same price in the interface may still differ by a few points, enough for micro P/L.

5. EA strategy logic (micro-scalping / trailing logic)

It seems the EA is designed to:

• Immediately cut losses via an equal stop loss

• Activate a trailing stop as soon as the position is in profit

• Exploit very small tick movements, spread changes, or execution behavior
