Hello molanis. I have this ea that when I use lot size of 0.1 then the
max volume of trade is 1 then the ea is very profitable. But the
moment I change the lots size to let's say 0.5 and max vol to be 2 then
the same ea on same symbol will be a losing ea. So I want to know
why this happens cos I want to to increase profit with more lots on same
symbol but it rather turn to loosin ea.

2. Also I want to know when the update of CIB for mt5 be released
that will include the use of specif indicator.
Thanks molanis

Your question is related to trading/money management not to our product. You are implying that if you made $15 in Monday using strategy A and double the lot size in Tuesday for the same strategy, you should make $30. In reality there is no way to know what you will make in Tuesday. The overall profit depends on the lot size, the number of winners and losers in the day and tp - sl .

Even if you double the lot size and backtest it again, you won't make the double.

MT5 updates will be released before the dead line for 2011 MT contest.

Thanks for ur response. But want to clearify that the issue I have is
With my ea and I know its not ur product
Now let me explain what A̶̲̥̅♏ experiencing. If I test an ea on a particular
symbol (gbp/usd) for period of let's say 6 months and have just 7 lossing
trades. Why will increasing the lots size and retesting for same period now
same period of time on same symbol now give double or more losing
trades. I thought it shud give same number of losing trades just dat both
the loss and profit of the second testing will be increased. Would have loved
to pull up the trade results and chats of what A̶̲̥̅♏ saying now but A̶̲̥̅♏ not
close to my PC now. Will do that asap. But I guess you now understant the
mystry A̶̲̥̅♏ trying to solve. Thanks

Have you notice that once in a while, even testing the same ea, same periods, same variables you get similar but not the same answer?
Backtesting is just an approximation - it uses sampling to run. It may change the sample.
In your case the number of open orders activated by the trading logic is different.
You start with 0.1 to 1 (10 orders) - then you use 0.5 to 2 (4 orders)
