Maximum number. 

50 orders, 100 orders, 1,000 orders, like that.

Thank you so much, Mohamad. 

Sorry for my poor explanation, I don't want to limit it by code. 

I'm wondering if I make a huge number of pending order, will the system reject to open new pending order by a maximum limitation.

  1. Likely.
  2. On my MT4 I get zero.
  3. There is no need to create any pending orders.
    1. The pending has the slight advantage, A) you are closer to the top of the queue (filled quicker,) B) there's no round trip network delay (filled quicker.)
    2. Don't worry about it unless you're scalping M1 or trading news.
    3. Humans can't watch the screen 24/7, so they use pending orders; EAs can, so no need for pending orders, have it wait until the market reaches the trigger price and just open an order.

There is. With a proper broker a limit order does not have any negative slippage. Downside is you aren't guaranteed to get filled.

There are other things to consider.

-There can be margin requirements for pending orders, you can run out of margin before reaching the maximum of pending orders allowed by your broker.

-Most if not all brokers also have a limitation on trade operations, this limit can not be obtained through the terminal. This means when you modify your sl/tp on your 200 order grid on every tick, trade operations can run up quickly so you will have to consider trade logic to prevent this.
