Help In Establishing Sequence of Events

[johnsund]

Am having trouble with coding so that in order for a trade to be valid certain conditions of independent indies must be met in sequence. Am able to get the indicators individually to work correctly, but need help in finding a way to establish something like the following:

1. Indie "A" has a set of parameters and specified conditions that have been met;
2. The EA then looks at indie "B". If the specified setting is not met, then no trade. If the specified setting is met then the trade is valid and it is taken, EXCEPT
3. If the specified setting is not met for indie "B" within "X" numberr of bars or in a settable period of time then the trade is not valid and the EA must then wait until a new sequence starts with indie "A" meeting the specified conditions again to restart the sequence.

I hope my problem is clearly identified and that someone can help. Can provide specific indies and settings if that would help.

Thanks for any assistance.

For two phase tests like this, I generally use two boolean variables LookingForBuy and LookingForSell. In the code that checks Indi A, have it set these as appropriate. Then when checking indi B, your code would be something like:

Code: Select all

If (LookingForBuy)
   CheckBIndicator for Buy

{ trade stuff}

if (LookingForSell)
   CheckBIndicator for Sell

 {trade stuff}

The trick is turning off LookingForBuy and LookingForSell if time or bars limits are passed. You can just record the stop Date/Time or Seconds in a variable when you set them, and keep checking that. For example:

Code: Select all

//indi a said to buy
LookingForBuy = true;
SignalExpires = iTime(NULL,PERIOD_M1,0)+600; //get the start of this minute and add 10 minutes to it


//later
if (iTime(NULL,PERIOD_M1,0) >= SignalExpires) {
   LookingForBuy = false;
   LookingForSell = false;
}

Or something like that.

I have adopted this construct:

TradeLong = true;
TradeShort = true;

if IndieA Long conditions fail, then TradeLong = false;
if IndieB Long conditions fail, then TradeLong = false;

if IndieA Short conditions fail, then TradeShort = false;
if IndieB Short conditions fail, then TradeShort = false;

if TradeLong = true, then send a long trade with whatever else is involved
if TradeShort = true, then send a short trade with whatever else is involved

From this, you can see that a trade will trigger unless any of the requirements fail. This is working well for me at the moment.

Good to see you getting involved in actual coding John. Sing out when you need more help.
