This has to do with your broker's stop loss proximity to current price limits.

Some brokers have 10 points limit, some others 0 and many other levels.

This "feature" is called freeze level and it prevents market book manipulation as well as reducing server load.

You can't move stops (or pending prices) closer to the market than the minimum: MODE_STOPLEVEL * _Point or SymbolInfoInteger(SYMBOL_TRADE_STOPS_LEVEL).

On some ECN type brokers, the value might be zero (the broker doesn't know). Use a minimum of two (2) PIPs.
