Hi, supporters!

Last trading week, my stretegy always slipped over my entrance point in realtime trading. I thought that was slippage reason initially, but no matter how big slippage it takes, the problem still there. Today, I spent a whole weekend day to find it out, finally, I busted the bug at last!

First of all, we build a simple strategy: Open at market below a specific price.
Image

We pick up last trading day's data as the sample, and assign 5 consequent specific prices. After composing strategy in VJF individually, put these 5 strategy's codes in JF platform to test, and these strategies should take the entrance at these prices separately:
1.3360-0.0010=1.3350
1.3359-0.0010=1.3349
1.3358-0.0010=1.3348
1.3357-0.0010=1.3347
1.3356-0.0010=1.3346
...

Unfortunately, the first four strategy's Calculation blocks couldn't figure out these entrances, which means executing 5 times strategy one by one, and just last one works.
1.3360-0.0010=failure
1.3359-0.0010=failure
1.3358-0.0010=failure
1.3357-0.0010=failure
1.3356-0.0010=1.3346 done!
...

But, if we get rid off the Calculation block away, input the entrance price directly, these orders taken perfectly! So, that Calculation block has calculating blind area.
Image

In particular, the tested area that we picked, is Australasia trading time in light volatility market, no big news issues out. And it is among the transaction-intensive areas, 1 mini-lot. So, there is no any excuse that no rivals to trade, or it should be slipped over.

You can download the strategy.vfs to test, of course you can test any day's data one pip by one pip, you will find out there are a lot of blind areas of calculation. Don't take it in VJF to test, just like I said: in VJF test, everything is well, in JF test, everything goes hell :lol:

Please fix it, thanks for your attention, and waiting for your reply!

Oh, my god, the new update still unresolved this issue! :cry:
It's really weird! Who can help me figure it out what happened? Which step blocked the calculated number? How can I bypass this bug, and keeping my strategy goes on...

Hi, dirk!
What's going on there exactly? Is there nothing that the team can do, or it is not the most critical defect? Please give me some info, thank you.
