WHYWHYWHY · 2019-01-26T08:09:07+00:00

why I set the system to start trading if barindex > 100 but it keeps starting trade from the first candle??? where’s the problem?? DEFPARAM CumulateOrders = False RSII = RSI[5](close) MA = Average[100](close) //long long = (BarIndex > 100 and RSII MA) short = (BarIndex > 100 and RSII >= 70 and close < MA) if long then buy 1 contracts at market endif //short if short then sellshort 1 contracts at market endif //exit SET STOP PTRAILING 50

```
DEFPARAM CumulateOrders = False

RSII = RSI[5](close)
MA = Average[100](close)

//long
long = (BarIndex > 100 and RSII <= 30 and close > MA)
short = (BarIndex > 100 and RSII >= 70 and close < MA)
if long then
buy 1 contracts at market
endif

//short
if short then
sellshort 1 contracts at market
endif




//exit

SET STOP PTRAILING 50

Try below, the default preload bars is 200

Let us know how you get on?
```
DEFPARAM Preloadbars = 0
```
PS I guess we can expect a few more WHY’s from you? 🙂 Catchy and memorable username! 🙂

Couldn’t resist a tweak … tried a few and ended up at below to keep it simple.

Results attached with spread = 4.

Need to do some Walk Forward testing, but I’m setting it going on Demo Forward Test as is anyway.
```
//https://www.prorealcode.com/topic/barindex-problems/

DEFPARAM CumulateOrders = False
 
RSII = RSI[8](close)
MA = Average[90](close)
 
//long
long = (RSII <= 30 and close > MA)
short = (RSII >= 70 and close < MA)
if long then
buy 1 contracts at market
SET STOP PLOSS 250
endif
 
//short
if short then
sellshort 1 contracts at market
SET STOP PLOSS 250
endif
```

thanks for your advice, but i have another problem

i supposed it will buy a contract at the first bar but it didn’t.

WHY?
```
once trend = 0


IF NOT LongOnMarket AND trend = 0 THEN
BUY 1 CONTRACTS AT MARKET
trend = 1
ENDIF
```

Try your code without “NOT LONGONMARKET”.

If you want to buy on first bar of the strategy, try with “if barindex<=1”
