    They all (including iCustom) return a handle (an int). You get that in OnInit. In OnTick (after the indicator has updated its buffers), you use the handle, shift and count to get the data.

  3. trade.Buy(.10,NULL,Ask,(Ask-200* _Point), (Ask + 150 * _Point), NULL);  

    You buy at the Ask and sell at the Bid. Pending Buy Stop orders become market orders when hit and open at the Ask.

    1. Your buy order's TP/SL (or Sell Stop's/Sell Limit's entry) are triggered when the Bid / OrderClosePrice reaches it. Using Ask±n, makes your SL shorter and your TP longer, by the spread. Don't you want the specified amount used in either direction?

    2. Your sell order's TP/SL (or Buy Stop's/Buy Limit's entry) will be triggered when the Ask / OrderClosePrice reaches it. To trigger close to a specific Bid price, add the average spread.

    3. The charts show Bid prices only. Turn on the Ask line to see how big the spread is (Tools → Options (control+O) → charts → Show ask line.)
      Most brokers with variable spreads widen considerably at end of day (5 PM ET) ± 30 minutes. My GBPJPY (OANDA) shows average spread = 26 points, but average maximum spread = 134 (your broker will be similar).
