If solana crosses 19 take a long, there will be a huge breakout, worst case scenario if it is false breakout you will loose 3*leverage
For trades like this enter with small amount with 2-5 leverage based on your risk if breakout happens slowly take small trades at 20, 21, 22.....with 5-10-15 leverage, keep your trailing stop loss in profit too if false breakout in start you will loose roughly around 6-12% on avg for small amount
Worst case senior if the coin goes in other direction, ie if coin goes below the 18/17 price then take a short setting your stop loss at 18.5 with small size and apply the same as i told for long
This should happen roughly in and around 2 weeks, once breakout you will be in profit for the coming months
