The first thing to do when trading contracts is position management

Within 5%

You can enter in two batches, one as a top-up (recommended)

Or you can enter directly, either you lose or you win, if you're wrong there is still a way out

But never add to a losing position

Going further wrong will only lead to faster losses

Forget I said anything about gambling

Second

Do not lock in long and short positions, under the guise of hedging

What is locked in is only losses, and you will still incur losses

Third

Do not believe anyone who tells you they can trade for free on a Karami exchange, the only outcome is liquidation, the free ones are the most expensive

Their characteristic is a very high win rate, heavy positions, if such skilled traders existed, would they need to take you along? Earn a hundred times, deliberately let you go against the trend once and it all resets to zero, (will watch your liquidation price and deliberately make you go against it + heavy positions + adding to positions)
