Help with MA cross and price crossing another MA

Bravestar100 2021.12.27 23:07

Hi all,

This is my first attempt in a very long time at writing an EA. In summary my EA should execute a Buy/Sell if the 1- and 20 EMA has crossed in the previous 10 candles and at the point when the price crosses the 200 EMA. I've done my best so far but when back testing does not pick anything up. I'm sure I've done something stupid as I look at charts and can seethis trend happening a few times when adding indicators manually. Can anyone help please?

Perhaps you should read the manual, especially the examples.

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

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 shows average spread = 26 points, but average maximum spread = 134 (your broker will be similar).
