How near can I set pending order from current price?

Is there something at symbol properties I can look at for this?

See if this function can help you:

You have to verify that your stops and/or pending orders abide by the Stops Level and Freeze Level conditions set by your broker's contract specifications.

HELP, failed cancel order [Invalid stops] problem!

Also read the following in detail ... The checks a trading robot must pass before publication in the Market

Especially these points:

  • Setting the TakeProfit and StopLoss levels within the SYMBOL_TRADE_STOPS_LEVEL minimum level
  • Attempt to modify order or position within the SYMBOL_TRADE_FREEZE_LEVEL freeze level

    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 (broker doesn't know.) Use a minimum of two (2) PIPs.

     
    And make sure your broker has Stop/Freeze level at 0 points. If not. Say bye bye to broker.
