Write them to a file. Take a look in the help files and you'll figure it out.

Good luck.

Hi
can somebody guide/teach me how to put Price label and Text properly.I already search and found this

Putting an object anchored on the right side of the screen

Code:

      if(ObjectFind("P label") != 0)
      {
      ObjectCreate("P label", OBJ_TEXT, 0, Time[0], Close[0]);
      ObjectSetText("P label", "Price", 10, "Arial", Red);
      }
      else
      {
      ObjectMove("P label", 0, Time[0], Close[0]);
      }

Code:

ObjectCreate("Trade", OBJ_LABEL, 0, 0, 0);
   ObjectSetText("Trade", "n", 40, "Wingdings", Red);
   ObjectSet("Trade", OBJPROP_CORNER, 1);
   ObjectSet("Trade", OBJPROP_XDISTANCE, 30);
   ObjectSet("Trade", OBJPROP_YDISTANCE, 30);

But still do not know how to apply.I attach together this indicator for my study in coding

Example like picture below,this is what i want,thanks!!

Code:

varlot=NormalizeDouble((AccountFreeMargin()*(varRiskPerc/100))*AccountLeverage()/MarketInfo(Symbol(),MODE_LOTSIZE),2);

where varRiskPerc is the % you want to put on your trade. ie 2%, then varRiskPerc would be 2. varRiskPerc MUST be a double or the formula will always return 0.

I want to grab the highest and lowest values of an indicator over an entire chart. A while ago I tried what I thought should have worked, from within an EA, but it didn't.
(Sorry I don't have that attempt now to show you.)

Any ideas?

You could use an array then load it up with values. Then do a simple sort to move the highest value to the top. Then do the same for the lowest.

For example you'd compare item 2 to item 1. If 2 is higher put it in item 1. Then compare 3 to 1 and repeat to the end of the array.

You'd just do the initial loading of the array in the init() function then with every new bar just compare the value to item 1 of the array.

Hope that helps

Hi

I need to write ea which will put awaitng order and do the following when it triggers:

1. Variables ("buy"/"sell",position1_lots,position2_lots,position3_lot s,entry_price,stoploss,TP1,TP2)
2.Open (buy/sell) trade with 3 positions at (entry_price) with (stoploss).
3.Close position_1 at (TP1) and move stop loss to breakeven for 2 left positions.
4.Close position_2 at (TP2) & let the last one ride or hit breakeven.

I've programmed some indicators but i really dont have much idea how to write this robot.

First find the bar with the ihighest array
then, use the bar and the findings in logical order for your indicator.

Hello everyone.

I'm trying to code in an effective and reliable invisible stoploss, trailing stop and takeprofit into my EAs. So far, my code just looks for the bid/ask to equal the stoploss or takeprofit value. If the price equals that value, then close the trade.

The problem I'm having is that sometimes the price seems to skip. There is no progressive movement of price. How do I then get around that problem? and make an invisible TP/SL which is guaranteed to close the trade where necessary?
