I would like to help with this function you are talking about but it seems I can't simply figure out your logic. This really has nothing to do with other logic of the strategy .
I would simply like to know this.
If you have 1 lot buy at 1.4110 and 2 lot sell at 1.4200. At what price you think you have 6 pips gain?Hi Christina,
back to your example:
but there is a line at approx 1.4175, where 2 sell lots (profit up, market down) and 1 buy lot (profit down, market down) are price equal (breakeven 0), so at 1.4169 6 pips profit are ready - then i would close all orders

Hi Christina,
back to your example:
but there is a line at approx 1.4175, where 2 sell lots (profit up, market down) and 1 buy lot (profit down, market down) are price equal (breakeven 0), so at 1.4169 6 pips profit are ready - then i would close all orders
IXBecause my example is 1.4110 and 1.4200. Here's my calculation:
First of all, at 1.4170(not considering spreads) we are break even. Now we have 2 lots of sell at gain at 30 pips each and 1 lot of buy at loss of 60 pips, so break even in dollar terms.
If exactly with my example, you should have 6 pips of gain overall at 1.4164.
At at 1.4164(not considering spreads) we have 2 lots of sell at gain at 36 pips each and 1 lot of buy at loss of 54 pips, so gain of 72 pips from sells and loss of 54 pips from buys. Overall for the group of trades, you have 3 lots with a gain of 18 pips. So it's more reasonable to consider now you have 6 pips gain.
However things will be complicated again because of spreads. Because if bid is 1.4164, ask maybe 1.4166, so your sells only have 34 pips gain each. Overall for the group of trades, you have 3 lots with a gain of 14 pips. So now in fact you have 4.7 pips gain.
If I take this example one step further, if we have 2 buy and 3 sell. Then at 1.4164 you break even.
If we don't have to consider spreads, then we need 30 pips total gain to have 5 pips of gain on each lot. So The 6 pips gain would be at the price of 1.4134, is this correct?
You system probably won't have this kind of situation, it's the principle I want to get. Do you agree with the above calculation?

i agree, you are 100% right with both calculations!
Hi, Michael,
I'm way too busy for the last couple days, I've already done this but needs more time to put together. Will post it here once I find some time to do so in the next few days. Chrisitna

Hi Christina,
no problem, take your time, i always appreciate your suggestions!

i need help
Hello, everyone !
This is my idea：i need 2 indicator buffers in separate_window,1 is devupBuffer[];2 is devdwBuffer[]. For example if have five digital 1,2,3,4,5 they average is3.Then the data is greater than the average of 3 4 and 5 devupBuffer={【（4-average）*（4-average）】+【（5-average）*（5-average）】}/Standard deviation(1,2,3,4,5)*Standard deviation(1,2,3,4,5).Data is less than the average of 3 1 and 2 devdwBuffer={【（1-average）*（1-average）】+【（2-average）*（2-average）】}/Standard deviation(1,2,3,4,5)*Standard deviation(1,2,3,4,5).
why can't this EA buy or sell?
hi, i'm really new to this programming with Meta... please help...
I'm working with a system on Stochastics with two levels, 25 and 75...
ONE trade only...
if the MAIN and SIGNAL are both below 25 and crosses, BUY.
if the MAIN and SIGNAL crosses above 25, CLOSE BUY.
if the MAIN and SIGNAL are both above 75 and crosses, SELL.
if the MAIN and SIGNAL crosses (no need to be below 75), CLOSE SELL.
that's it...

hello, I'm really new to this mq4 programming but I've read codersgurus tutorials (thank you so much!) so I think I can understand something... However, I've made this EA that's based on MOVING AVERAGES... BUT IT'S TERRIBLY NOT WORKING THE WAY IT SHOULD BE!
the rules here are very simple...
1. MA_04_1H (means moving average period 4 for 1 hour timeframe) crosses above MA_14_1H,
confirm it with MA_04_4H being above MA_14_4H (the trend is upwards) ------> BUY!
2. MA_04_1H crosses below MA_14_1H,
confirm it with MA_04_4H being below MA_14_4H (the trend is downwards)------> SELL!
3. when MA_04_1H crosses with the MA_14_1H, close that order (it can start a new order given rules #1 and #2)
4. one trade only... (if BUY, close that BUY. after that, SELL if necessary)
I've made 2 functions: Crossed, and Confirmed.
Crossed is for the 1 hour timeframe.
Confirmed is for the 4 hour timeframe.
can anyone help me debug this thing?
